I've been having nightmares and restless dreams for this past week and last. I think a lot of it if due to stress... but not really sure. I can't really remember them all but last night I had a dream that this really large fat man with yellow teeth was wrecking things in my room and in my dream I had a box that he was going to dump out, I don't know what it was, but apparently my dream self didn't want him to dump it out because I yelled out no. It woke me up and I was still in dream world and waking up because I could still see him kneeling in my room when I woke up for about a second, but then I screamed and he disappeared and I woke up with my heart beating fast and breathing quickly. The dream didn't disturb me as much as seeing him still there.
I don't know why, other than I've been extremely stressed out but the nightmares each night are just getting worse and worse. I think I am only getting four hours asleep a night.

i've had nightmares like that before. these also happened on little to no sleep.

once i was dreaming there was a bunch of huge bugs crawling around really fast in circles on my carpet, and i woke up and could still see them on the floor, i jumped up and onto my bed and leaped off and ran out of the room. took a few minutes for me to go back in and still i hadnt realized it wasnt real. so i was searching for them for a while wondering where they were hiding. it actually took me a few days to understand it was a dream.

and just last night i dreamt of myself laying in bed at that very moment, and i placed some circular object on top of me over the covers, then i woke up and began frantically searching for whatever it was because it had gone missing. this lasted a little bit, then i laid back down and was out again. but i remember it clearly.

i'd also like to know why these happen to us!
