It seems like he was reading his mind
I believe he had a flashback, maybe he's really strong and that resulted in an accident...
he def has the ability to read minds/see thoughts cause it was showing him how the other guy wants to go home and eat the meal the grandma prepared for him (which he mentioned before & is why he wants to get everything over with). he probably saw a traumatizing memory of the other guy, likely related to why he wears a helmet, and couldn’t handle it.
I'm having a hard time processing what happened when the helmet guy touched him. Did the masked guy read what was on the helmet guy's mind(?) or something when he touched him or was he just having a flashback of some sort(?)
