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.

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".
