Yellow is a wavelength moths don't respond to.
Wow, weird.
I have heard someone here on ATS suggest that the bright tunnel of light when you die is coming out of your mother's womb in the next life (ie reincarnation). Or maybe it isn't that bright, but just the "spiritual world" (whatever/whereever it may be) is 'brighter' than our world is, and it takes some getting adjusted to, much like flipping on the light for the first time in the morning. Some people will go as far as to say that we are beings of light and actually made of light, just at a different energy vibration level.
