I relate to much of what you wrote. I also have experienced dreams that I thought were real upon waking. They were horrifying type dreams and if what I dreamt had actually occurred, I would be able to survive it. I don't think you are losing it completely (to reassure you) but like me, you probably need some help with this. I wish I could be more helpful, with specific ways to cope, but my coping strategies probably wouldn't help others. Be kind to yourself please.
