Dream of

Ok so in my dream i fall in love with this girl she is a figment of my imagination never met her irl but heres the weird part today when i went to school theres a new girl and she looks/sounds exactly like the one in the dream and now it gets weirder she kept looking over at me and i dont know if mutual dreams exist but i dont think they do but even so it was as if we had the same dream but from the others perspective
