Last night I got 9 hours of sleep and meditated before bed and did everything that I was supposed to and still cant remember a single dream... Very upset right now. Here are some of the things I think could have effected it but I don't know. Before yesterday I used to smoke weed everyday, I heard that THC impairs Rem sleep but I didn't smoke yesterday, last time i smoked was the day before (I quit now). Also last night I fell asleep with my contacts in, could this be the problem? I don't know but its very frustrating to have like no dreams.
