Redditor Hardtopickaname came up with the interesting theory that Homer has actually been in a coma for the past 22 years. Actually, there is much evidence in support of his theory.
#2 So... is it all a dream, or what?
The theory suggests that most of the show has been a dream of Homer's – which could explain some of the crazier stuff that has happened along the way.
#3 Where it all began
In “Homer the Heretic,” Homer has a conversation with god, suggesting something bad will soon happen to him:
Homer: God, I gotta ask you something. What’s the meaning of life?
God: Homer, I can’t tell you that.
God: You’ll find out when you die.
Homer: I can’t wait that long!
God: You can’t wait six months?
Homer: No, tell me now!
God: Well, OK. The meaning of life is…
#4 Later, at the hospital
6 months later, as promised, Homer is in the hospital. During his stay, a vending machine falls on him and he winds up in a coma. At the end of the episode he wakes up – or did he really? Redditor Hardtopickaname thinks otherwise.
#5 Strange happenings
Perhaps Homer never woke up from that coma and the rest of what happens in the show is just a dream. That could account for the characters never aging, the celebrity guests, and some of the more unrealistic situations that occur from time to time.
#6 The plot thickens
Also, the redditor noticed that before the coma episode, the themes of the episodes were more grounded in reality. Afterward, the outlandish situations began to emerge, such as the time Maggie shot Mr. Burns.
#7 Remember when?
Other strange happenings: Mr. Burns capturing the Loch Ness monster, the time Homer went into outer space, and Homer's work with villain Hank Scorpio. These are only a few examples of the many, many strange events since the coma episode.
#8 Wrapping it up
The redditor concluded that he thinks the meaning of Homer's life, which is what Homer had first asked about when he saw god, was to entertain.
