I believe there is a place where we go after death. Where we ALL go, not only the good guys. I think it's a place where we get some rest before our next life (I believe in reincarnation). I don't believe there is such place like hell.

And about the spirits... Yeah, I believe they (maybe not ghosts but there definitely is something) exist. When I was a child and we lived in our old apartment I heard things nobody else did. It happened nearly every night after the lights were turned off. I heard there was someone in the kitchen - sweeping the floor, doing dishes, glasses clinking like someone was constantly rearranging them, the sound of footsteps, the water running - one or two people bustling around. Now when I think about it it's a bit scary but then I thought it's normal and everyone can hear it (we lived there since I was 3 or 4 so it seemed like it was always there). I believed the angels were just cleaning up to help my mom since she was working all day and had very little time for anything else . When I was telling my mother about it she was just smiling and saying "Oh, that's very nice of them, I don't have to do this tomorrow then". That stopped when we moved to our current apartment and I just forgot about it. It came back (the memories, not ghosts) not so long ago when I was thinking about my life there. I don't know what was it but there for sure was something.
