senses illusion in a human body how people look at the same picture and each will see a different colors 1

no less than 15 power point slides, it should cover most of the human sense,hearing, seeing, and smelling

ex: the dress pic that some people would see a blue/black dress and some would see white/gold dress.

ex: the voice note that repeat a word some would hear Yanny, and some would hear Laural.

how does that happen and what makes our bodys react differently to some actions?
