omg my head is tingly all the time, and during my menstruation it gets worse!
Japers. I will answer the sleep aspect of the post. I will leave day 14 of your cycle until menstruation to someone else. Not exactly an area I know much about. I take it you are on medication for your stress? Medication can, at times, bring about nightmares and the user would no doubt jump up in a sweat, panicing and the likes. My doubt is the stage of sleep. i think you are more experiecning lucid dreams. they are the type that seem so real, that when we wake up, it takes a few minutes for us to cop onto the fact that it was just a dream. If you were dreaming dogs were attacking you in a lucid dream or anything with pain, you would really think you are feeling that pain. But lucid dreams occur either just as we go to sleep or when we are about to awake. Thus we are between both states. Not 100% asleep, but not awake either. Hence they appear more real. Because part of the mind is aware of the wakened world too. Twenty times a night? I assume you would awake each time? Hence I am thinking more lucid dreaming. This would occur with someone who wakes and sleeps, wakes and sleep, etc, etc. I might be way off the mark too. No expert.
