I've noticed that if I'm calm 2 hours before I get into bed i'm relatively calm and can sleep with few ectopics, heart palps, racing thoughts or uneasiness. However I find that when I get into bed straight from a long, stressful day full of anxiety and I haven't done anything to mediate it before bed I get hypnic jerks, like just as I'm falling a sleep, I get this sweeping anxiety jolt all over my body followed by some heart palpitations, this causes me to wake up or breath hard and then it's normal. Then I try to fall asleep again. then just when I'm getting knocked out the same jolt of anxiety, almost like a chemical rush goes into my body and I feel super anxious, get the heart palps, jerk a bit and wake up.Eventually I fall asleep. Anyone ever experience this? Is it true that if you did solve this its becuase you worked out, did yoga, mindful meditation, maybe smoked a joint before going to bed or a few hours before calmed yourself down ?
