Is it normal to not really believe in life after death but...

wonder about some paranormal things are unexplainable? For instance children who seem to be able to remember their past lives and later find out the person they're remembering actually existed? I also read a book where someone psychic supposedly knew things they couldn't have worked out about a murder. The book was written by the victim's father and I remember the case being in the news so I know it wasn't made up, and I can't see why he'd just invent that part when the rest is true? I mean there's a perfectly obvious explanation for most of the ones you hear about, but not all of them.
