Well, now when you said it I realised it happens to me also. Also without Ivermectin.
I just thought that's normal. Before sleep for instance, laying in comepletely dark room but you have
beautiful warm glowing light in front your eyes shut, or like in your head.
For few seconds, than you open your eyes - it's dark,
but close again and the glowing is back. I don't know if it is like that for you but it's cozy and nice.
Also if you sneeze or cough in the dark it's like inner explosion of light, like firework.
Once I asked my husband if he sees it but he replyed I'm probably just nuts.
Anyway, thanks for the amazing sesssion once more
