I sometimes experience Hypnagogia, particularly when I am very tired, where I have vivid hallucinations in my mind’s eye in the period between wakefulness to sleep. I have no conscious influence over the arising images; I am just an interested viewer, with no mental presence internally voicing opinions or conclusions.
I also have experienced, although more rarely, a Hypnopompic state of mind between sleep to wakefulness, where I briefly have no memory of my life or where I am – I am just there. That sounds scary in the default settings of everyday life, to lose identity and a life story, but my overriding sense is feeling at peace, just before my thoughts come flooding in and layering everything on top.
