I had a dream where I was thinking of shell commands in my bed and then I did a haunted shell command and it summoned a ghost. I had sleep paralysis so I was stuck in my bed. But then I realized I was dreaming so I was able to start walking again and then I walked into the bathroom where my brother was taking a shower because there was light in there (and I couldn't see the ghost when it was bright) after that I woke up.
