Lately Ive been experiencing vibration in my body when i sleep. My head has pressure, tingling sensation, i hear swooshing sounds. I wake up it stops but when i go back to sleep it starts again. as if im having an outer body experience. I researched the signs that my crown chakra is opening. but I havent been meditating. Why is this doing this on its on. Just started a week ago. Feels weird when I sleep and LOUD.
