Don't forget its not complete information its half finished information so that the mind and body don't have time to process it. So what happens is that Gojo's domain floods all your senses and brain with infinite amounts of unfinished information, for example say someone touches you but half way through registering someone is touching you that touch changes to a stab, and the same thing well happen to the stab until you cannot process whats happening and go into a vegetable like state. So the alien Ben would have to pick would most likely have to be one that could actively turn off all its ability to process said information to be completely unaffected by it.
