38yr old white male: Yes, I have suffered from this for many months, and truly years off and on. Most times it occurs between 9pm-12am. I need not be in bed, but getting ready to wrap up the night while lying down watching TV or in bed - A SURGE of TOTAL FEAR courses thru my body, on a 10 scale, about a 7-10, and it is truly frightening.
My blood pressure will skyrocket 20 pts for no reason, believe me when I say I have had more tests than most people can have - no tumors, tilt table negative, 5-6 MRI's negative, etc, etc - but I do suffer from a severe vestibular disorder and have literally been dizzy for 3 years straight. It has almost disabled me entirely.
So my answer is YES, others do feel this - likely a corabination of mass stress/anxiety accumulated throughout the day - adrenal release of some sort.
