It was night, I was in a bar with people flying all around instead of walking properly. Barman gave me a glass of juice, so I drinked it, but the glass was infinite. Then the ground started shaking a bit and I heard a creepy music comming from toilettes. I went there to check out. First, I checked the women ones, there was just a basin turned upside down and a drops of water were falling up on the ceiling. I went to check the men toilettes and opened the door. There was a xenomorph standing right in front of me. I woke up, but I still heard the strange, creepy music for a while.
If you don't find this creepy, that's okay. It's no longer creepy for me either. The problem was that back then when I was 11, I found xenomorphs scary as hell. Another problem was that I also couldn't Lucid dream back then as I do now. I'm lucky to still remember this one (the dream was still longer, I just don't remember it whole).
