I agree with the person above me. The only spin I have on it, is when he says "Such a surreal place to see so how did this come to be
Arrived too early": tells me that there was an accident or something where he lost a pulse or what have you, and arrived in heaven. Then it goes on to say "just giving you a small taste
Of your afterlife here so stay, you'll be back here soon anyway": Tells me that the person he is conversing with knows that it's not yet his time to die, but he will be back soon, meaning that when it is his time to go, he will be back in heaven. So the person is trying to convince him not to return to his body, but to stay.
