I had a bizarre experience early this morning.
3 different times the ringing (Schuman resonance) dropped in pitch to
a lower vibration.
One of the times I felt off balance for about 3 seconds.
Did anyone else have this sensation?

Yesterday, standing in my kitchen at 11:11 am getting a cup of coffe. My ears were ringing and I felt like I was going to tip over, ears ringing continue and then I felt normal again.

Yes,
I have been experiencing this off and on for about a week now.
The intensity of the ringing gets louder and drops in pitch for about 2 or 3 seconds and then goes back. It has made me unsteady a few times, but not like feeling like passing out. It feels different.

I thought I maybe having a panic attack, because it was just so unsettling. Ringing in my ears has been going on a while! Glad to hear I'm not the only one. Good to hear from you Charlie!
