Very rare zero recall night. Flutterings of fragments from middle of the night wakings, but nothing solidified. Failed BTS at about 5-6 hours, got into deep relaxation but just could not fall asleep, thus missing the major dreaming phase of the night. Got to bed late (1-1:30am). Going to bed after midnight fairly reliably means less recall. Need to establish a regular bed time. Tonight! I remember my dreams!
