So sometimes when Im falling asleep I get this weird feeling, is like waves of unconscioness or darkness (not religious but is my best shot to describing it), they start light but when I'm falling deeper it gets more intense and fast and I feel numb in my arms, I can at all points get back to complete awakeness but when is stronger is more difficult and I get this strong feel of fear if I get too deep. The waves start at the top of my head and is way more usual in naps, even with my eyes close I can feel my sight going darker, I have traied going to the end but I can't control de fear of going to deep. They started like a year ago and they were very frecuent at the begging but now it's not as usual. Have you ever experienced this?
I'm sorry of any misspelling I'm not native speaker
