I had a reoccurring dream about two years ago, I was actually browsing NT in my bed with the TV on, it was around 2 or 3 am. I was watching the news and they were talking about an alien attack, they were following the aliens in a helicopter and I noticed it looked like my area. I hopped up and looked out my window and sure enough there was commotion outside, helicopters shining their lights everywhere and fire everywhere.
I heard a noise in my living room, hopped up with the quickness to go see, where my back doors were was completely ripped off of my house and there was fire in my backyard. I took a step outside and looked left and immediately saw a dark, shadowy figure with tentacles. I screamed in shock/horror, but nothing came out of my mouth. I sprinted back to my room and grabbed the knife that I kept on my bookshelf and ran back to kill the alien and that is when I woke up every time.
The first time I had it I woke up with my computer in bed with me and the news on, I was shook, I literally ran to my back-doors to see if what I dreamed was real, it felt too real while I was dreaming.
I had the dream maybe 4 times, and on the 4th I realized I was dreaming, the only thing I did differently was instead of going to my room for the knife, I ran to the kitchen which was much closer. Don't know why I never had it again.
I want to try lucid dreaming soon, I'm gonna start writing down all my dreams right when I wake up in the morning.
