Hey Vitamin A... I know you don't mean to sound skeptical, but when you say stuff like 'that's a little freaky' and 'that's almost hard to believe' it comes across that way and will have the opposite effect you desire. I love hearing stories about other people's "memories" too, but that's all you're probably going to get out of this. You can't MAKE yourself remember past lives and nobody is going to be able to tell you how to do it. I know that's what you're looking for, but you need to just sit back and enjoy the sharing experience.
And what you said about dates and people, you're looking for info to substantiate the validity of reincarnation, right? Well, you're not going to find it. I don't think it's provable. You either believe in it or you don't. It sounds like we all do, so far. Maybe you could try meditation. I think those "memories" are locked behind some kind of "door" in our mind. Maybe meditation is the key for someone actively searching for those memories.
And... just because you don't remember any past lives right now is no reason to assume that your soul is young. And... the thing about the woman coming out of the building, I think that was more of a psychic thing, like clairvoyancy maybe. One more thing... do you feel an affinity for any particular place and/or time period? eg, ancient greece, ancient rome, ancient egypt, the middle ages, 1920s chicago, 1960s california, the orient... do any major historical events completely fascinate you like WWI and WWII, the british civil war, the american civil and revolutionary wars, the napoleonic wars?
