Thank you so much. I will definitely give these steps a go. It's very persistent whatever it is. It even appears doing exactly the same thing when I'm dreaming. I once woke up not being able to move except my head was moving very fast from side to side & the mist was right above me. It was frightening & draining. I was quite shaken after I got up & didn't want to sleep in the bedroom for ages. So I will definitely give this a try. Thank you!
