I experienced mild hypothermia the 2nd winter I lived here alone on my farm in the country. We had an ice storm & the electric went out. I didn't have a generator or a space heater that could have helped & didn't have wood for my fireplace. My neighbors farm had 22 horses & he had just gotten remarried & was living an hour away on a normal drive without ice so I had to feed & make sure the horses water had the ice broken so they could drink. By the time I got back in my own freezing house, my cloths were ringing wet from sweating that lugging hay & getting it to all the horses caused. I wrapped up in a blanket & surrounded myself with my dogs & started shivering so bad I couldn't stop. The thought hit me, it's better to get out of the wet cloths & put on dry freezing ones to warm up in than to freeze to death in the wet ones I had on. I braved it & as quickly as possible got cloths to change into. I couldn't even take a hot shower because my propane tank was empty & no electricity to heat water.

After changing cloths & bundling up in blankets I think I did fall asleep. No idea for how long. I never had any psychotic experiences during that time but I did have a horrible panic attack that hit. I was blessed because I had charged my cell phone the first night sitting in the police station lobby in town. My friend called me at 4am to see if I was ok & she talked me through my panic attack until the sun came up.

It's a scary feeling & hypothermia is nothing to mess with. Usually after warming up & getting to a safe place there aren't any bad residual effects except for possibly medical ones.

I would honestly depend on the professionals for determining what is really going on with you. I would tell them about the experience but with my own personal experience with hypothermia I wouldn't bank on it being the reason behind what you are experienced.
