List RulesVote up the most twisted theories about 'The Big Bang Theory.'

Weird TV fan theories can be extremely entertaining - maybe Saved by the Bell is Zack Morris's dream, or That '70s Show is a sequel to Happy Days. While some of these theories are fun, others are seriously dark, such as these Big Bang Theory fan theories. While not all are terrifying, most are at least peculiar. Some of these theories try to explain Big Bang Theory characters, such as why Raj seems to have selective mutism or why Bernadette's character grew angrier with each passing season.

Whatever the theory - and based on how messed up some of these hypotheses are - there must be a lot of fans out there who think The Big Bang Theory is super creepy. Here are some of the weirdest and darkest fan theories about the hit show.

    Sheldon Is In A Mental Institution, And The Show Only Takes Place In His Head

    Redditor /u/thetheoryguys claims Sheldon is in a mental institution, perhaps even for offing his father and his father's mistress. They go on to say that both Sheldon and Leonard are in this Los Angeles facility - Leonard was admitted there after being lobotomized by the government for giving up secrets to North Korea. The show's other characters are also residents or doctors there.

    According to the theory, Penny is a failed actress who turned to substance use and sex work before ultimately landing in the facility; Amy is a neurologist who works at the institution, and she feeds into her obsession with Sheldon by studying his brain; Raj is a doctor there instead of an astrophysicist, at the behest of his parents; and Howard is the facility's "caretaker" who occasionally engages in intimate activities with Raj because he can't seduce women.

    Redditor /u/Pick234 claims that Howard's mother doesn't actually exist: "Howard [is] just crazy and lonely and uses ventriloquism to speak for her. Also, all of his friends like him so much and either A, believe him or B, don't want to break it to him that she isn't there, either out of love, or fear that he would snap."

    Bernadette Is Actually A Series Of Clones

    Redditor /u/ConspirOC believes that Bernadette has grown angrier and more disrespectful throughout the course of the show. Rather than attributing this change to her stressful marriage, the theorist claims the Bernadette seen on the show is actually a series of Bernadette clones, created after her immoral research organization experimented on her. The Redditor stated: 

    Every time she is regenerated, she remembers that she is a clone and is spliced with the memories of the old Bernadette, but part of her remembers and resents Howard for entrapping her in a marriage she didn't want and knowing she won't live long enough to grow to love him before she is [eliminated], despite him being kind of an *ss. She always remembers that she loves him but can't... feel it.

    Redditor /u/Sarahmint's theory makes the troubling claim that Sheldon is a sociopath based on his behavior: "Sheldon is highly intelligent, very selfish, and understands human interaction to the point of being highly manipulative while remaining uninterested in people who cannot be useful to him in some way."

    They continue: "He used his gf as a human shield and talks about Queen Bees to his female friend while lying that it has nothing to do with her social life, when it clearly does."
