Hello OP. I was woken by my father on Sept 11, 2001 shortly after the first plane hit from what I recall (It may have been after the 2nd plane but I'm pretty sure it was the first). I was out drinking the previous night and woke up still intoxicated. I was in my early 20s and I think unemployed at the time, although it's possible I was working in customer service. To coincide with your other thread, I experienced a transcendental, supernatural upheaval in my life in late Nov 2014 and through early 2015. It was very analogous to being let out of "Plato's cave" (another comparison I saw you made and one I have made previously to myself and others about the experience. There were many interesting themes of birth/rebirth and metamorphosis. I wound up being taken by the police to the hospital with what I'm relatively sure was diagnosed some sort of psychotic episode. It was the first time anything like that has happened to me in my life (non drug induced). I have a rather large chunk of missing time during that hospital stay as well.
Later in Dec 2014 I wound up back in the hospital for a short time after basically getting caught in a "endless loop" in my mind. There are many more details I could go into if I choose about the transcendental experience. As a result of it all, I wound up evicted from my place of residence in the southeastern US and moved back to the northeastern US where I was born and was located during Sept 11th. I'm not that interested in the "Mandela effect" idiosyncracies, but I have had experiences where I thought I had 'changed dimensions', once during the 2014 experience and another time in the late 90s. I'm relatively sure I have information about this entire whatever we're calling it now that can be of significant assistance and valuable contribution. Unfortunately, I've been banned from this site from my home, so I am at another location posting this message.
