I once heard the reason we see "the light" when we die or pretty close there. That it is the brain shutting down and just expelling the energy. Is this true? How does it work?

We dont know exactly, but the current working theory is that the brain pulses extremely strongly when dying, which produces extremely vivid images, including the famous "light at the end of a tunnel".

I've read that, as the brain shuts down, it is flooded with a chemical called DMT, which creates a euphoric and other-worldly feeling.

Something I heard is that peripheral visions dies quicker than central vision for the tunnel aspect. I should probably verify it though
