My first experience with Morrowind was 2 years ago on the Xbox. I had made my way to Balmora with my Dark Elf character, browsing the shops. I came out of one of the stores and a thought came to me as I walked through Balmora. "I'm going to start floating in a minute, my character can walk on air." I promise you, and I utter no single word of a lie my character shot up into the air and started floating, when I realised that this was impossible he fell down and died.

Is this a well known glitch? I almost convinced myself that I suffered with some type of Personality disorder. I had no active effects.

I was playing in third-person.

There are a few glitches in the game which make the collision go crazy. Usually resulting in you falling through the ground and dying. It's just a rare, random thing.
And the Xbox version is known for being less stable than the PC.

I have seen the "shoot up into the air" bug before too, but it was caused by a modded collision box. But at least it proves that it could happen in the vanilla game too.... So I guess you just got lucky.

Well i guess some idiots characters just do what they want

How interesting! Thank you very much for that information. I suppose coincidences like this happen at least once in a lifetime, how very strange.
