In the last month nearly every night I’ll be drifting to sleep when I suddenly get a bright flash of light which I wake up to and have a sensation of fear and anxiety it happens about 1-3 times a night, I’ve also had a dream of my legs vigorously moving up and down and then waking up to them slowly stopping, and sometimes I feel myself slowly moving out of my body but never fully just like a weird floating sensation... if anyone has experienced this or can help pls tell me!:)
