i have no idea if its true or not; for the sake of anyone who lives with him (myself occasionally included) i hope it is.
however. when he’s sleeping off a few injuries and is pain-medicated enough that its effective on his jacked up metabolism, he does.
which would not normally be a big deal. thor sleepwalks too, and the only problem with that is he sleeps naked. so i thought nothing of it when peterbird wandered into the common room late at night with his eyes closed. he kinda just showed up and then stood there, so i figured id let him be and went off to go make myself some hot chocolate. ten or so minutes later, i stepped around the divider wall back to the common room.
and promptly had the everloving daylights scared out of me.
why? you ask, why were ten precious years scared off your ridiculous life, bucky???
well. because parker was standing right on the other side of the wall, about two inches from my face. with an alarmingly vacant expression on his face. because he was sleepwalking.
