My first LD lasted 5 seconds, but this one happened last night.

I went to sleep at 10:30 and woke up at 3:30. I read stuff here for like 1 hour, then i took some coffee and went to bed again. Some minutes later, i tried focusing somewhere in my mind when suddenly some flashing lights, most B&W started appearing in my mind. 5 seconds later I started hearing some strange sounds. I heard something about hypnagogic imagery and sound in WILD threads, but I felt i was like too conscious that i would wake up, then i relaxed(maybe too much). Then the imagery stopped and i was in my room again.
There was a jar of pickles in my desktop. I remembered "hey! this wasn't here before!" and then maybe I detected I was dreaming. As i tried to get out of the bed, my body was incredibly heavy and difficult to move. I suddenly woke up and then went to sleep again. Then i was again in my room, but i could move easily, then i started to float, then doing some slow flying. I was kinda conscious. There was still some strange stuff, like rooms that didnt exist. I couldn't recall the ending of this dream, but it was awesome, as i didnt have flying dreams in like 4 years.
