The experience I and some other ppl I know had was like:

Child Me: what is heaven like?

Them: you're always happy all the time because you're near god and singing his praises forever

Me: but wait like what about playing or doing stuff I like doing now?

Them: well you wouldn't have a body anymore, and you'd like doing those things because you'd be in heaven then. It's like being in church forever, but you always feel happy and loved because you're with god.

Me, disturbed: What about my friends and my parents and family?

Them: yeah they'll be there if they were good, but they wouldn't have bodies. If they were bad theyd be tortured in hell for eternity by demons.

Me, more disturbed: and I'd still be happy despite that?

Them: basically, yeah

Me, super disturbed: god sounds like a seriously bad dude and everything you've said is terrible
