Dizzy Facts

You don't have five senses, you have more than that. You can sense the direction of gravity. The organ that senses the direction of gravity (what way is up or down) is called vestibular system, it can be found deep in your ears.

JellyFish have a similar system, if one is born in a  micro gravity environment, they become dizzy after  they're brought back to earth. The sudden introduction of gravity causes them to get vertigo.
