Inside your ear is a tiny organ called the vestibular labyrinth. It includes three loop-shaped structures (semicircular canals) that contain fluid and fine, hair-like sensors that monitor the rotation of your head. Other structures (otolith organs) in your ear monitor movements of your head — up and down, right and left, back and forth — and your head's position related to gravity. These otolith organs — the utricle and saccule — contain crystals that make you sensitive to movement and gravity. For a variety of reasons, these crystals can become dislodged. When they become dislodged, they can move into one of the semicircular canals — especially while you're lying down. This causes the semicircular canal to become sensitive to head position changes it would normally not respond to. As a result, you feel dizzy.- Inside my head it is amazing, I mean, there is a maze, or labyrinth. - A vestibular labyrinth, which is very alliterate of the amazing labyrinth in my head. - My mind is a minefield, with pretty crystals in it. - These shiny things make me sensitive to movement and gravity. (Which makes me wonder if my superpower of flying is the culprit in all this Vertigo madness.)- It seems as if I have dislodged my crystals.- Note that I did not say I've lost my crystals! I've lost my crystals! I'm no Tootles. They are merely dislodged.- This makes me think of an avalanche.- An avalanche makes me think of rocks.- So basically, according to the Mayo Clinic I have rocks in my head?- In other words, Rolling Stones. (Which makes me wonder where I put my iPhone? Where's my iPhone?)
