Im not sure if this topic would link in with lucid dreaming, but lately ive been having several strange 'turns' whilst going to sleep (which i expect would be in the same category as the 'falling' sensation). The first, which is most common, happens about 5 minutes after getting into bed, before i'm actually close to reaching sleep, and consists of a massive buzzing sound shooting past my head, followed by chills up my body, a fast heartbeat (probably from the sudden scare) and a short headache.

The second (which happened about a minute or 2 following) was one that i hadn't had before. It was as though I had suddenly been dropped into a dream although i was still awake. Basically, I was overcome by uncontrollable vivid flashing images of for some reason, a football video game that i was playing several days ago along with some sound to go with it as well. Of course, being shook up by this one, I opened my eyes almost immediately after it began.

After these events last night, I had some very vivid and full dreams, and was actually questioning myself as to whether i was dreaming or not at one point, although i came to the conclusion that i wasn't. I've read about lucid dreaming and everything that goes with it in the past but i'm not so experienced or knowledgeable on the subject, so maybe someone else on here has had similar experiences or knows what these were?
