Based on your description (this CEV totally goes away in light), and the wiki entry describing the various levels, I’m probably at Level 3. Long ago I thought I was losing my mind (some days, I still do, I suppose), but now it’s all just kind of vaguely amusing, vaguely interesting movies that don’t make much sense.
Over the years I’ve worked on…
… and sometimes I wonder if it was my early years with CEV (since I was 10 or something) that led to my interest in lucid dreaming.
