Not to muddy the waters, but psychosis for me felt like my subconscious flipped inside out. My brain was in a dream like state and functioning as though my conscious mind was not in charge even though I was awake. I was watching myself through part of it and each action was made immediately without rational thought.
I experienced what you might call archetypal experiences and my worst fears came forward. Also, things I was confused about spiritually were a theme as well. Additionally, repressed rage from abuse and trauma I experienced as well as my anger over abuse others had suffered came forward.
I'm going somewhere relevant with this, I promise

I started to wonder if psychosis at least for some people could be assisted if we could better understand why it presents the way it does and then do some sort of psychotherapy to lessen the effects. So I did a little research to see if my hunch that what my husband and I were 'watching' the night of my episode was my subconscious mind on display. There is some weight to it actually. I found several studies and this article mentions it as well.

Now the part that is relevant to this thread... Several of us have experienced the 'man or person behind us' hallucination or similarly the hallucination that we are being watched. I am wondering if this is a symbolic representation of something seeded in the unconscious due to trauma or other negative experiences. I'm thinking maybe it holds significance the way certain experiences do in dreams. I have zero dream interpretation expertise, but I'm curious. My therapist is pretty good with it, so maybe I'll get a chance to ask her when I see her tomorrow.
I am sure there are multiple interpretations, but I found this:
To dream of being watched means that you are feeling under the microscope, as though all of your actions are being recorded. This may indicate that you feel confined in your work environment or personal relationship. You are lacking privacy and feel you are being scrutinized or criticized.
Many of us here can certainly feel like all of our privacy has been stripped away. We are constantly being scrutinized and analyzed by our treatment teams and our friends and families. We are even analyzing and scrutinizing ourselves like I'm doing now.
Just something I was pondering this morning. I'm curious if that resonates at all. Of course ignore it if not
