Dream About Dark Presence And Waking Up By Slap

I had a dream i was in my old childhood home and i felt a dark presence, i couldn’t see or hear the dark presence but i could feel it and im in the home with all the lights off, its like sunset time so its not super dark outside but its on its way to be dark outside. the only light that is on is the stairwell light to the basement. but i dont go down there as the dark presence feels stronger by the basement stairs. i go to the top floor instead. when i get to the top floor i walk towards my childhood bedroom. then i’m suddenly woken up out of my sleep by something that felt like a hard slap across my face which made me fly to the opposite side of my bed, but when i look around there’s nobody else in the room with me.
