Usually, my dreams are just a jumbled mess but from time to time, they are so vivid and real that when I wake up, I can't distinguish if it was reality, if it really happened, or if it was just imagination freaking out. Sometimes, I go through these deja-vu moments then because I actually dreamed about things happening before they happened and it all gets terribly confused. I never feel so scared like when I have one of these dreams.
