O.K, last night I had a really bad and fitful night's sleep. The silver lining was, though, that with many interruptions and night-time disturbances I was able to try WBTB (or something similar) quite a few times

The result was that I had a lot of time with some great (and often quite beautiful or surprisingly clear) hypnogogic patterns/images. It seems that since practicing LDing I've had more and better pre-sleep imagery like this (another cool effect from greater dream awareness). A few times these patterns seemed to bleed into full dreams, and on a couple of these occasions I was lucid. The downside was that even though I was lucid I seemed weak and unable to control much, and that these dreams were so unstable that they lasted only a very short time (dreamlets?) before I woke again. I suspect this was because of the bad night I was having and how tired and stressed I was.

Oh well, at least I've learned that a) greater dream awareness enhances hypnogogic imagery, and b) that pre-sleep hypno stuff can be turned into LDs.

All I need now is a decent night's rest with unbroken sleep!
