I kept on having a dream where I would see a shadow chasing me. Then once that thing caught up to me it turned out to be this little cute and fluffy dog but when I walked up to it to pet me it's head grew huge with giant teeth and I woke up before it could eat me.

One of the reasons why little dogs scare me but I'm also afraid of little dogs since hal of them enjoy humping me when I try to pet it.
