This is bothering me 😞

So i had an insane dream.... this is how it went: i was in the car w my friend and we just got done shopping. We were driving back to my house and this guy was standing/walking on the side of the road. He looked at me right in my eyes and flicked me off with both hands. So we get to my house and hes standing on the side of the street i told my friend to just run from my car to the house.... so we started running and she got in.... i was standing infront of the class door and saw his reflection right behind me. I opened the door and he grabbed me. I couldnt say anything at all. I couldnt scream. I woke up at this point and was shaking and my heart was pounding. Does anyone know what this could mean?
