dreams

do you ever dream about things or people that you only see or talk to ? well the random thing is that this happens to me all the time. like yesterday I got bored so i kicked somebody and they came after me so i hid and they found me. so when i went to sleep I was dreaming about them. when i got up i couldn't  get over it  because it was so crazy. so now i have my own theory if you do something that gets stored into you memory( not your short term one), you will either remember it the next day or (in my case)you will dream about it. randomness cant get any closer than that.
