Well, since I'm a Christian, I don't believe in the "afterlife" I believe in heaven and hell. Since I'm a Christian, I don't fear death. If I die, I get to see Jesus first, so I win. But, no one knows what heaven looks like. The Bible gives some details of heaven, like there is no death, crying, sorrow, etc.
"He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away." - Revelation 21:4
The Bible also says heaven, evidently, has rooms. Where, in heaven, you can have your own room.
"In my Father's house are many rooms. If it were not so, would I have told you that I go to prepare a place for you?"
There are hundreds of things the Bibles says about heaven, those are just the ones I could think off of the top of my head. So, what it will be like, I'm sure it will be amazing. I get to see my dead family members, praise God, never feel any pain, sounds like a great way to spend eternity.
