I had a dream that a man completely clad in black (black hoodie, black jogging pants, black sneakers) with no face was chasing me. He began chasing after he saw me and my dad(we were walking the dog) walk pass him and my dog (also black) began sniffing him. I pulled her away and told my dad to run, so we did. To me surprise, he began chasing me. After turning a corner, he took out a meat cleaver and threw at us.
I woke up after, and when I began to dream again my friend said that the man was her grandfather??? I've never seen her grandfather, and I couldn't even see the man's face...
Does this dream mean something, or is it just a strange dream? I didn't feel too scared though, I've had one scarier dream about wooden dummies.
