Sleep and the afterlife

I was coming home tonight from my mother-in-law's wedding (she got remarried) and on the 45 minute drive back to San Antonio, I began to think of how sleepy I was. And then, as I usually do, started thinking too much and wondered why we don't remember things when we sleep.

I'm constantly reading different books about religion, spirituality, and little about history. So I like to try and think of things that people may not normally think about. I'm sure someone has thought this before, but still... I wondered... If we have a spirit and die, then we are supposed to go somewhere. Some people believe in heaven, hell, purgatory, nowhere, etc. Either way, I thought, if we die, our spirit is released and we are still supposed to have some sort of conciousness. So basically, our spirit is separate from our bodies.

Well, if that was the case, then why don't we remember things when we sleep? I mean... our bodies are taking a time out... so where is all that spiritual activity? Does the spirit take a nap too? Granted, we dream, but most of the time, I don't remember my dreams. And they are usually so far out there (the dreams), that I know it is just in my head. I almost think it seems logical that if our bodies where sleeping, then they would be slowing down and basically nearing death (not really, but closer than when we are awake). So while our bodies are sleeping, shouldn't our spirit be able to roam around and see what's up around town. =)

Anyways, just another crazy idea from yours truly.
