Yes. It usually happens when I play too many hours in a day. When I go to bed it is like the game is burned into my brain that is connected to my REM sleep. So during tte REM episodes I am either still playing the game or have become the character, usually playing the same scenario over again. It’s usually a raid boss or something that I am learning and/or playing too much with multiple characters.
Go to Settings -> General -> Show FAB (floating action button). The action button has options including hide read. You can freely move the buttons
