I am pretty sure now a dream told me what was up also. One time in my life this happened. I woke up screaming ( out loud ) and there was a spider the size of my bed room window in the window ). My eyes were open and it was still there. It faded gradually. My room mate came running in. I never woke up screaming again but kept being woken up by the spider that faded away gradually with my eyes open. Nothing else like this has ever happened. I got sick for 10 years with CFS. As that healed ( mostly serious strict stress reduction techniques , hydration, and rubber band therapy on the wrist to stop thinking about it ) the spider was smaller and smaller then stopped. I lived in down town la, slept with the windows open fan blowing air in, helicopter all the time overhead. I know now a lot of malathoine at that time for mosquitoes. I never knew about it while there. Dr. S has a paper on that same spraying saying it has nanoparticles in the malithione they were using... weird, so much we do not know about our bodies
