Thanks! It’s a really interesting link. I’m now sure that I can hear the sound, but it only happens if it’s really quiet or if I focus on it a lot. Well, it doesn’t really matter if it’s a condition or not, after all it’s not disturbing me in any way.
But it definitely is there, and the WILD discussed in this thread gave me veeery weird HI last night.
I just remember suddenly seeing light flashes, and the rest was a lot more intense than the ‘normal’ WILD I try.
The only downside is that I forgot focussing on the sound and fell asleep.
