People will come up with a fan theory for just about any TV show these days.

Whether it's Spongebob Squarepants or The Fresh Prince of Bel Air, there's alway a superfan who's noticed something tiny and blown it out of proportion.

That's exactly how these Friends theorists started out. Fans began responding to a question by Twitter user Ted Fox, who noticed that on the DVD boxset of season four, only Rachel had her eyes open.

Serious question:

Why is Rachel the only one 👀?

The replies are where the crazy (and funny) really theories really come into their own:

She alone knows the truth. She has seen beyond the veil, and knows that there is no way she should be able to afford that apartment

She's plotting to kill the rest of them in their sleep

Chandler is spooning her. The answer is obvious.

Speaking of crazy...

Rachel had a breakdown, she moved into a mental hospital not an apartment. The rest are fellow patients
It was an elaborate coping mechanism

People, please. Maybe she just didn't get the memo to close her eyes? Or had too much coffee at Central Perk?

Trying to work out if it's actually all in Rachel's imagination will definitely kill the vibe of chilled Sunday re-runs.
