I was experiencing insomnia, but when i did sleep I'd. Experience. Such vivid dreams that when i woke i would experience. The most realistic hallucinations. Also on a fw occasions total paralysis, visions of a black cloud of some sort pinning me down an preventing me from calling out for help, sometimes lasting up to 5 minutes. I dont concentrate on the fear of the situation, rather more just trying to get up. Untill i started researching. Logical explanations, i didnt know what to believe.
