Inside your head it will echo.\n\nIf you hold a candle by one ear, you will be able to see it if you look through your other ear.\n\nDragon will tell you if you lost your mind.

I read about this.  It happens in bright light because the optical and nasal nerves are so close together.  The brain is receiving all these signals from both that are so close together that it can sort of trick itself.

The pressure would be higher, the temperature would be lower, the light would be less.

You could be right, at the verge of brain shut down you may see bright lights.  That's like they also say they feel warm, well that's from the loss of nerve cell connection, for an example, pinch a nerve, hot pain. So they could feel their nervous system shutting down.
