I've read plenty of things about lucid dreaming and astral projection (which is the long term goal) i started trying 3 days ago. I kept a dream journal but only remembered barely anything from my dreams let alone be lucid in one. I've tried reality checks (I plug my nose under doorways to see if I can breathe) but still no success, today is day 3 and I didn't even remember anything from my dreams. I've tried repeating to myself "I will lucid dream tonight" as I go to sleep. Can anyone help me plz?
