Yes.
But this is all taken from a purely psychological standpoint, where each of his friends and pokemon are aspects of his personality. This is surreal, as none of this actually is suggested in the series, therefore invalid. The author continues to over analyze a simple fictional anime character. Indeed, he may have been hit by lightning, but that happens to nearly every character in the series, shall I remind you of Team Rocket, constantly "blasting off again" in the fictional world, the pokemon themselves endure the same fate as Ash, being subjected to electrical shock, lightning or otherwise.
So, saying this is all his "dream" in his coma is lacking in proof. This is merely a "what if".
