strange & scary sensation as water drained out of tub

Has anyone else had a similar strange experience...

After my Epsom salt bath I just laid there until all the water drained out; but as I focused on the water level going lower I became disoriented and felt SO weird as if I was going down the drain WITH the water!!! It's as if my brain couldn't sense water touching my skin, so I couldn't comprehend why I was still there lying in the tub-I dunno-it was SO WEIRD-& difficult to explain

LOL! I've had that feeling - it's like there's a complete disconnect between the brain and the body. Kind of like your brain is on pause. I learned not to stay in the tub as the water drained! LOL!

I'm not sure what is going on when that happens though.
