Lately I've been trying really hard in the area of reality checking and keeping a dream journal and downloaded a lucid induction mp3. This all payed off as now my dreams are really vivid and I'm doing a reality check in a dream basically every night now...but here's the problem:

every time i reality check in the dream everything goes white and i wake up. My friend told me it's probably because I get overexcited which is probably true, but I'm not sure how to deal with it...
Has anyone got a solution to this?? I'm very grateful for any help
=D
