Had them from time to time, I seem to dream rather a lot but not really remember them after a while and I feel like I've had far more lucid dreams than I can remember.
One trick though, no idea if it helps or not and it is a constant annoyance to me is that I imagine a watch on a chain attached to a centre point of a circle. It doesn't have to be a watch, it just has to be something, anything usually appears to me as round though, attached somehow either by a solid line or a fluid line like a piece of string. In my head usually as I'm trying to get to sleep or as a dream I see this thing spinning around in one direction, over and over and over. I then try to stop it, which I find very difficult and usually end up gesticulating wildly or opening my eyes. But on the rare occasions where I can get it to slowly decrease in speed and go back the other way usually ends up with me either actually in a lucid dream as that's happening or I will usually have one that night. When I get it right it's so goddamn soothing seeing this thing slowly spin one way, then the other and back again.
Very bizarre and more often an annoyance than not but hey, I quite like doing it sometimes.
Also the background seems to be brick if that makes any difference whatsoever.
