Anyone know what this is, I nearly collapsed while losing hearing at the same time?

So i was in the shower and i gradually started to feel quite tired (not in the need to sleep way, in the exhausted kind of way) and decided to quickly finish up showering. A few seconds passed and before i could finsh up, i found myself turning off the water to get out (and wasnt really in controll because my body was just trying to get me to sit down). i started feeling really dizzy as i got out, looked in the mirrior and my face and entire body were completely pale. Had to lean against the wall because i felt like i was going to collapse. My hearing started to go and then was replaced by a really loud ringing (almost sounding like a fuse being lit but really ringing deeply in my ear). My stomach felt really sick but i didnt need to get sick at all. Started trying to walk out of the bathroom but was finding it hard to walk and my vision started to go completely blochy and i wasnt really thinking straight. got over to the bed and sat down and it all went on for a while and then slowly faded away and now i'm fine. I can remember the exact same thing happening a few years ago one day and again, nearly fainted, couldnt hear/see, or talk when people were asking me what was wrong as i was sitting down in the middle of the street where it was happening. Again, it stayed for about 2 minutes and then started to fade and i was fine again. Also breathing very deeply when it happened both times and coudnt really think anything accept basic kind of observational thoughts.

Dont think its anything of a big health scare because i feel fine after it and it happend a few years ago and nothing ever came of it but still, its such a thing that you cant forget happening so was just wondering what it could be.

Anyone else have this happen to them?
