Had this happen with one dude in college. I had no clue why he joined at all. He spent every session on his phone held 6 inches from his face, and always had to be told when it was his turn in combat, just for him to have no clue who to attack.
It's unfortunately common, just not necessarily everyone in the group. So, it's the best side effect due to the grounded reality that's suited to the wish.
This irritates your intestines terribly every time you use it, causing you to be the one to have to cancel every time tho, or play the session in agonizing pain and very frequent bathroom trips
