I had gone to bed around 2:30 AM, and I was trying to get to sleep. I heard what sounded like jets outside, but I had the strangest sensation that I was outside, I felt like I was outside, and the noise wasn't 'muted', so to speak, like it would be inside. This startled me, and I opened my eyes, and found myself back in my room. After that I fell asleep rather fast. Ended up having a blurred, yet very frightening dream of being in a facility, with insect type humanoids (might be the best way to describe it). I woke up with a start, scared out of my mind and just about to scream, luckily I regained consciousness fast enough to stifle it and not wake up the others in the house. I ran straight to the bathroom. It frightened the heck out of me! When I had come back, I looked at the clock, it was only 4:30, which I thought was strange.
