I was sleeping when i was woken to the sound of crunching wet gravel outside the window (i live in a bungalow and there is a a small border of gravel out side the window) and in my head was a mixture of clicking and muttering noises. the sound seemed like it was not just in my head but maybe in some kind of bubble around my head. the sounds were almost like trying to tune into a frequency but not quite on the right one. my head was off to the right and i was laying on my back still with my eyes closed but very much awake. suddenly my body was forced straight (still on my back) and my eyes forced open. i felt very much awake as though it was mid day. my body was retrained like something was holding it but it wasn't uncomfortable and the noise of the clicking a muttering increased not in volume but in intensity and the same time the crunching gravel noise outside the window was moving left to right as though something was pacing or swaying left to right. suddenly the noise stopped and the hold on me was released and instantly some vomit/mucus entered my mouth. i have never experienced this before but over years i have witnessed a large sphere shimmering in appearance in the sky. a low flying disc shaped object and suddenly afterwards in a photo there was a human shaped being in the distance but looked more shadow like. recently i have been doing more research on ufos, my need for answers has dramatically increased. unfortunately this experience didn't allow me to take any photographs but i would be happy to share other photos from past events if they could be of interest.
