Hello - I found this forum because of continual strange goings on with my son. It started when he was about 18 mos. old and we were house hunting in Tennesee. As soon as I got him out of the car he went to the edge of a hill pointing across the valley and saying 'Help, help'. He couldn't tell me more, because at the time he was not speaking yet, only a few sounds. I picked him up and he kept on calling for help. I even called my husband over and asked what he thought was wrong. It was very strange, only to get stranger. After we looked around the property for a while we went inside the house. When we asked the man why he had decided to sell at this point after renting the place for so long, he told us he'd recently lost his renter and didn't want to be bothered anymore. She was a young woman who lived alone and apparently died alone unexpectedly of brain cancer a few months earlier. That was the start of what I'll call some rather strange happenings. When Georgie was little we called him the Oracle because we'd be having a conversation and say (for example), "Do you think Kathy will take the new job?" and a little voice from the backseat would respond, “Nope!” and he was right most of the time. That has eased off now – our fault, he didn’t like being called “the Oracle”. We’d jokingly say, “Ask the Oracle” and he’s say, “I not Oracle!” so we stopped.
Lately though, he’s started telling us about past lives. It started one afternoon about 6 mos ago when he was playing with a firetruck. I said, “Do you want to be a firefighter when you grow up?” He said, “No, I was fire fighter last time and a boat driver before that – I want to be a boat driver again”. Lately it’s been, “I’m sad. I miss my old family”. I’ve tried to get details without pushing or acting weird about it, but he sometimes mixes obviously current stories in with his memories. He told me that he had lots of brothers and sisters and that his brother Tom took care of him after his family died in a fire. We’ve recently had lightening storms, and it seems that this must be how the fire started, as he is very afraid of the storms and keeps asking if the lightening will burn the house down. He seems to be telling us about several lives at once and none of the things he’s telling us are from TV or movies, with the exception of when he is pressed for too many details he adds things from his current memory, such as “My brother Tom used to sing “Little Mr. Roo” to me”, which is a song from a recent movie. And while he brother may have sung to him, it was probably not this song.
It is very clear when he is involved in his memories, he sits quietly, looking sad and then says something like, “ I miss my old house” or Mommy or family. I never anticipated this kind of behavior and did not bring it on because I wouldn’t have believed it, had I not seen and heard it myself. I’m here because I wonder what bearing it has on his current life? Does it matter? Is it important? Do I need to do something with it or about it?

Deborah has given you some great advice. Carol's books are excellent and I would definitely recommend reading them.
Have you tried pointing out to him that you are his real parents in this life? That his other parents were his real parents in another life? Sometimes when they start thinking about their past lives, they become a little confused. Time isn't as clear-cut to children as it is to adults. It could be a relief to him (and to you 
) to point out that he is remembering something that happened a long time ago, and remembering people he was close to before coming into this life.
