I had a past life dream?

Interesting dream I'm guessing it was a past life as you woke in tears and it felt very real to you. I dont' think you'll find out where or when though as you're meant to live this life you have now without too much interference from your past memories. I'm also guessing that although you said you heard your mum scream and the house blew up it was actually you with your nan that died and the scream was your then mum who saw what happened to you both . I think by asking her to get ted you saved her life not yours.You can ask to visit your old mum by thinking of her strongly before you sleep and asking to see her in a dream even if you don't remember the dream you'll feel it helps you understand the memories better.
