So, I had a couple of dreams about my crush...in one dream he ran me over

in the second dream, I was at the pool and he stole my towel, and then in the third one he sat next to me and bumped me with his leg (

)
SO I got the thinking, can dreams be signs of what's to come with your relationships, your future, etc. ?? I mean, these dreams are pretty distinct, and it's wierd I can remember every detail about them. Am I just being paranoid or can dreams really be signs?
