Season 4, episode 11 - a dog is heard being killed Season 7, episode 15 - a very cute small dog is killed for its heart to be used in a ritual

In season 3 episode 9 a dead and mutilated rabbit is shown. Multiple other animals die throughout the show.

Animals are intentionally killed throughout the series.

There is an episode where Crowley has his hell hound attack another hell hound, but they are both invisible. You can, however, hear the whimpers and see the blood.

Crowley's horse

Season 9 episode 5, some guy eats a live cat

*intense flashbacks to the episode called bugs*

Not like a drain"-dragon, but still.. Kind of.

The episode "Bugs" in the first season

Yellow Fever has snakes. Also season 14 Jack gets a snake and Dean is afraid of it

A major plot point of one of the seasons

Dean drinks a lot of alcohol and Sam gets addicted to demon blood, which is pretty much like a drug, in season 4.

The character Dean is an alcoholic. Alcohol is also frequently consumed by many characters.

throughout all seasons of the show there are scenes of characters cutting their palms or firearms for rituals, spells, ad sigils. The cuts are not often shown explicitly on camera and I the later season are healed quickly by Castiel. There are a few scenes of Castiel with larger cuts. One scene shows a sigil cut into his chest, and another shows a message carved into his chest by another character. Almost every character ends up with a cut at some point, most often from violence from a monster or another character.

Cutting off heads

Ruby is shown being tortured on screen, Dean talks about being tortured/torturing other people.

In the pilot episode Jessica, Sam's girlfriend, is also burned alive on the ceiling Although they are technically dead the ghosts and spirits are burned when their bones are torched, they are dead but they scream while they burn a lot of the time

Not explicitly shown; more of a mention or two. For example: 1x2 "Wendigo", 1x15 "The Benders".

The teeth aren't exactly pulled. There is an intention, but it doesn't happen. There is however an episode where someone loses all of his teeth. They just fall out

Many characters have their eyes burnt out throughout the series.

During the Christmas special there are teeth pulled and fingernails ripped off

Characters frequently are shown breaking bones on screen.

Parents die and the main characters mother dies early on same with their father later

Teenagers die more often than young kids but both do die, often violently or on-screen at least, this I suppose also goes for ghost kids which are sometimes 'killed' to dispel their spirit. Child death is also referenced

There is an episode where 2 witches are feuding because the husband cheated. There’s more cheating throughout the show, though not on the main characters behalf (It never explicitly shows them cheating)

in at least one episode, 1x19, a doll is burned to dispel the spirit of a murderous child. Nursery rooms are also shown burning.

Yeah there's a full episode very early on (Season 2) that's just... just all clowns...

A few one-off episodes; season 2 ep 17 stands out to me.

But not that many or particularly scary.

Hence the name *SUPERNATURAL* Practically always ghost 😂

All the time, major plot point, mostly demonic.

S4, E8 - Dean can be heard vomiting from inside the bathroom after getting food poisoning (20 mins). S5, E21 - There's scenes where a doctor vomits, and patients and doctors have vomit around them. Castiel also coughs up blood in this scene (After recap - 7 mins and on). S6, E5 - Dean vomits blood concoction (37:40). S8, E12 - Henry Winchester can be seen vomiting after getting out of the Impala (10 mins). S8, E14 - Kevin can be heard vomiting, no visuals (5:30).

Sam and Dean go to an abandoned institution and patient abuse is discussed. For one episode Sam and Dean are in a psych ward. One character is shown being in a psych ward.

There's a scene in an abandoned asylum in which a ghost uses what is essentially electro therapy to harm a character

Including a very thick vintage style needle.

One episode has a woman who has brain cancer and a man who had brain cancer but was cured.

There's def some manipulation by characters throughout the show. Particularly by Lucifer and Ruby. Some of the angels are rather manipulative too

Dean has flashbacks. Bobby has a panic attack in one episode.

Several scenes take place in a small concrete cell, in walls, in crawlspaces, and in the trunks of cars.

Dean overdoses and dies momentarily (can’t remember the season). Crowley stabs himself with an angel blade to save the Winchesters (last episode of season 12). Boy shoots himself (season 1). Angel suicide bombers exist in season 9. (all I can think of off the top of my head, may be more x)

Sam, Dean, and other hunters often cut themselves for rituals.

When Dean has flashbacks they are shown as flashes of light.

The GhostFacers do have the camcorder recording style

There is lots of talk of abortion for a couple episodes, with the main characters trying to convince Kelly Kline to abort her baby because the dad is Lucifer, but ultimately Kelly decided to keep the baby.

Although nothing is explicitly shown, at the end of season 12 there is a childbirth scene.

Jack's mother does happen to die during childbirth though.

Jacks mom dies as she gives birth And shows dead pregnant people in one episode

In season 7, there’s extremely strong alluding to Sam being raped/sexually assaulted by Lucifer when he was in the cage. He’s also plagued with ptsd and hallucinations of Lucifer which constantly make him feel unsafe, and cause him to be unable to eat and sleep

a lot of innuendos and sexual jokes. Some sex scenes but nothing too bad.

In Season 4 Episode 11 “Family Remains”, it is said that a father raped his daughter, leaving her pregnant.

A few angels are briefly misgendered because they inhabit vessels of a different gender.

Charlie, a cannon lesbian, is stabbed and left dead in a bathtub. It's extremely sad

One early episode is based in a very racist man being killed by a black man, and his ghost runs over black people with his truck. Confederate flags are shown in a few episodes.

Practically every single black character who served an important role is now dead. The ones that bothered me the most were Gordon, Rufus, and agent henrickson, as their deaths did not push the plot foreword at all

there are several in the later seasons, particularly when it comes to the Leviathan entering the scene

In earlier seasons, Dean makes comments to Sam of like "can you be any gayer?" And lots of homophobic jokes are thrown around but less frequently in later seasons

Hitler is briefly risen from the dead, but is quickly killed. None of his ideals are appreciated or adopted by any protagonist characters. There is a Jewish character, Aaron if I remember correctly, but he is not portrayed in an antisemitic way. Crowley, when he was the king of hell, has a portrait of himself in Nazi uniform with an insignia of a pitchfork in place of the swastika. He does not hold antisemitic beliefs or values. Jewish folklore is mentioned several times throughout the show, but never in a derogatory way.

Santa and Mrs. Claus are shown as their original beginnings as pagan gods, killing people for sacrafice.

!SPOILERS! God is defeated by Jack, who quickly fills the position. Cas is in The Empty (SuperMegaTurbo Hell), and stays there until being briefly mentioned by Bobby in the last scene. Dean dies while fighting "clown-vampires", getting impaled by a large screw sticking out from the wall (OSHA Violation). Sam lives on, without his brother and starts a family, but eventually dies of old age. They are reunited in heaven. Cas and Jack are absent for the finale. Not necessarily sad (more bittersweet), but extremely disappointing for long-time fans.

In season 7 episode 10, it shows Bobby’s early family life. His father abused him and his mother emotionally and physically. There are themes of domestic violence throughout the show. ( A kid literally whipping herself through emotional manipulation, multiple spouses killing eachother (though one is usually a monster) etc.

Several characters are hit by cars. The Impala is hit while Sam and Dean are in it.

Sam and Dean were abused by John (some is shown in flashbacks, it's verbal/mental and heavily implied physical abuse as well as neglect), there are episodes where children have been/are being abused.

In season six when the boys go back in time to the wild west, a man is hanged for murder.

One of the early episodes of Season 1 shows several individuals drowning.

Sam and Dean use guns in almost every episode and kill people with guns frequently, including shotguns.

Mostly kind of bad/cheesy special effects but there are people being attacked by hellhounds, being beat, dying on screen, etc.

An episode in season 1 revolves around a demon infiltrating planes and crashing them. One of the main characters is also terrified of flying.

One scene early in the series involves a serious car crash in which nearly all the occupants are killed.

Spoiler for later seasons: It technically didn't happen but Dean was going to bury himself alive in a box at the bottom of the ocean - he at the time would have been kept alive, possibly forever, by the angel Michael. He has a long dream about being trapped in the box that shows his fear
