I despise that theory with a passion: it reminds me of the limbo/purgatory theory that's popular among the Ed, Edd n Eddy fandom. It's pretty obvious that Satoshi (Ash) isn't in a coma for various reasons, and it irks me that the theory is mostly used as a way for people to explain why Satoshi doesn't age.There was a theory according to which Ash was in a state of coma after the lightening strike or spearow attack on the first episode and everything after that is just coma induced dream. I find this theory quite strange because, no way a 10 year old can think of so many people he hasn't seen in real life.
Also that's quite dark for an anime like pokémon.
