Sleep is not only a wY for our body's to rest and it is also a time for our minds to reboot you could say. I also believe this is the time our deeper parts of our minds go where others do not believe in. Someone who believes in life after this and in the ones who can fore see things . I wouldn't get into it, you may think I'm one of those nuts , but I'm just a 55 yr old woman woman who has a family tray of this who for many years fought it. I started reading Sylvia Browns books to understand myself. That helped alot. No I do not go out a give readings but keep a journal of my dreams where I met my love ones and of future things that will happen that I have to figure out. This is the only way to prove to my family. If they do, and they have seen it and do try not believe but then admit it. I love it when they have to admit it, they hate too.
