i think i may have experienced this the day before xmas. its an odd thing to describe but i didn't really feel scared of anything, as someone mentioned above it was more of a lack of emotion more than anything. i remember feeling like i was sinking into something deeper in myself and afterwards it felt like my self consciousness was pretty much out the window. i mean i was aware of what was happening, but not in a judging way, more like an indifferent/curious way. like i remember i would ask myself why i did certain things; like why i looked away from the lights when i turned them on or why i walked the way i do.
i remember that i became pretty interested in just about anything, and uninterested in things i would normally be interested in. like for ex i walked into the bathroom and was looking at the mirror and i noticed this black thread on my coat, and i began trying to figure out why it was there for quite awhile though i never figured it out. but thats when i noticed that when i walk in front of a mirror normally, i always look at myself. but i could've cared less about my own reflection, and more about why the mirror was there in the first place, what holds it in the frame and questions like that about what i normally wouldn't give two thoughts to.
i don't know how long it lasted, time felt like it had slowed down, maybe something like a half an hour or 45 minutes, but i know it started to happen a day or two later when i was watching a football game. i could feel myself starting to sink into myself again but i kind of choked it off and stopped it from happening. see it wasn't scary when it happened, but afterwards it was scary to me bc it felt like a different type of consciousness and i didn't want to be that way around other people. since then i haven't been able to get back there successfully. i feel like if i meditate, or self inquire then i become more aware of things, or feel like i am partially feeling what i did that night, but i haven't gotten back there to the same degree.
after reading the description of numinous im not sure if this is the same thing or not, but it did to me feel like a spiritual presence or a deeper level of conscious, i mean i don't know one way or the other. but i wrote about it in better detail in my journal so i could remember more specifically what happened.
