So I have been having these things for years now where after 1h-3h of going to sleep I wake up in this weird feeling. It used to be lot more intense and it felt like a panic attack but nowadays its something else. Basically my muscles feel very tense and heavy. I have trouble moving cos I am holding my breath and really scared to breathe. Usually my head is humming and theres this pressure in my head for a while. I feel otherworldly and scared for a while. I do not feel my body the same way, everything feels very distant and my limbs feel light when i move them but also heavy. 

This is not like pure panic where my heart rate goes up, my pulse is usually quite normal. Mainly I feel that otherworldly feeling for a while and might get extremely scared and overwhelmed by all the noices around the quiet room. I am able to move my body like normal but it is hard because im stiff with fear and moving around feels overwhelming. Also I do not "hallucinate" anything so I think it is not a sleep paralysis. This could have something to do with my stiff neck or just my anxiety and stress showing up at night? :(

Thanks for reading!
