After a near few death experiences, my perception of the world just seems off. Like more dull and dark. Every once in a while, I get a small glimpse of what it used to feel like and it seems so much more real and full of light. I heard of another person on Reddit feeling the same, but I couldn't get ahold of them. Has anyone else felt this? I need to know if it's normal. This has gone on for about 2 years.
