God man, you're freakin me out how similar it is how your lucids came about to mine. I first started having LDs my freshman year of college (I'm a senior now) when I would take a nap in my dorm room in between classes. At first, I had no idea what was going on...they went away for awhile and would come back every now and then and then just about 6 months ago came back strongly...I joined this site, and have been happily LDing away ever since We're just naturals like that...you are so lucky. Anyway, I know exactly what you are talking about when you said that you thought you were actually moving and might fall off your loft...but don't worry...thats what sleep paralysis is for, it paralyses you so that you CAN NOT act out your dreams, although it often feels that way. I remember one lucid I was having in particular where I stopped doing what I was doing (you can imagine what I was doing) because I thought that I might be doing this in real life and that my roommates might see it, so I made myself wake up and I was just lying there like normal.
