LOL You won't explode, so don't worry about that. Memories have a way of coming out when you least expect it, but if you want to have some kind of control over the process, ask your T if she practices hypnosis or knows someone that does. That way, there's someone controlling which memories you are ready for. Sometimes they just come out, but your subconscious has a way of letting out the most important ones.

I was semi-hypnotised so that I could remember some aspects of my childhood.
