What should I do if I have a strange encounter at night?

During the night the night on random occassions, i would open awake from my sleep but i am not able to move at all, it is as though i am being held down by someone. i try my hardest to move but i can only just about move my ankles. i even try to open y mouth and start praying but for some reason i cannot do so. so anyway after struggling i tend to start praying in my mind by this point i am usually fully awake and know what is going on ut still i am not able to move! i strat praying in my head and roughly after about 5 min i am able to move i get the feeling as though someone has let go of me 

this has happened to me on a few occassion's especially during ramahdan but happened to me again the other day i wanted to know if it were the jinn/shaytan holding me down or was it just scientific 

usually when i am able to move it is as though a crane have been lifted from above. i struggle very hard to move but i am not able to speak nor am i able to move. 

during ramahdan i also had dreams where by my lil sister or someone i knew had jinn inside them, but when i was infront of them for some reason i was not able to read out loud my mouth woul dbe closed but i start reading out loud in my head. maybe this could be related.
