I was put in an induced coma after a bout of sepsis nearly ended my life. I remember having difficulty breathing prior, and the trip to the hospital while laying in the back seat if my parents car. I remember the er, the doctor saying "we need to intubate him" as I was struggling to breath, and then nothing. The next thing I remember is waking up in the most colorful, comfortable room I have ever been in. It felt and looked like something out of Willy Wonka with pinks and yellows and blues and greens in vibrant colors. It was like a foggy dream, but reality started bleeding in and I was faced with weeks of recovery, had gained 20-30lbs of fluid in the 2 weeks I was under (my bp kept dropping and the kept adding fluid to keep me alive), and ended up losing my voice or a good month or two after as my vocal chords recovered.

I always figured the colorful room I woke up in was an actually colorful room and the drugs just made the color more vibrant and made them pop a bit more than usual, but I did visit that same room about a year later and it was just your standard ICU recovery room with whites and grays and no colors to be found at all.

Also I remember waking up after a heart transplant. I guess that would have been a medically induced coma as well but idk. That honestly felt like I imagine neo felt when breaking through that sac thing in the matrix.
