This little piece of shit comes whenever it likes

What title says. I've had a crazy weekend, I think I had about 4 pretty long ones over 2 days and some lesser ones or echoes or whatever. And some very weird experiences. I am now absolutely certain what Super-O is and that I've had them before with varying length and intensity. I still don't know how to make it come though but I think knowing what to expect already made it easier to welcome it again when it came around.
