I am sorry for the delay.
When you are in REM sleep your body is naturally paralyzed, if you are awakened in this rem sleep you will not be able to move and may feel all the things you have described, this is called sleep paralysis and is normal:-) As far as the other symptoms, this could be a hormone imbalance due to perimenopause. Neutropenia ( low white blood cells) can be present in normal healthy people, especially in black or Arabic and Yemenite Jews. Some possible causes of low white blood cells include Vitamin deficiencies (megaloblastic due to b12 and folate deficiencies) and leukemia. I would recommend you see your gynecologist for the menopausal symptoms, sometimes birth control can help with these symptoms. There are also a host of holistic approaches...here is a link for this:
