Hi! I'm Theresa (obviously) Welcome to the forum.
That sounds like a pretty frightening dream- I absolutely hate the ones involving death of my family members; they're the worst, aren't they?
If you're looking to improve your dream recall, you should start a dream journal. It'll help you recognize the patterns and familiar occurances in your dreams so it's easier for you to become lucid.
Anyway, I hope you like it here. Any questions, feel free to PM me, too.
