I suffered through several months of insomnia and endured several of the side effects, you describe. I would be awake, but if I closed my eyes, it was like being in a room with all kinds of strange people. I met with a sleep specialist at University of Louisville Physicians, who referred me to Dr. Ryan Wetzler who has expertise in insomnia related sleep disorders. He treats in person or by video conference. drwetzler@sleephealthlou.com. Last night I got just over 8 hours sleep and I don't see the strange people anymore. I highly recommend him.
