"Big Brother" Season 8 winner Evel Dick Donato is convinced a car SMASHED INTO HIM Friday night in Ireland ... and his injuries look really, really bad.
Dick posted a photo on Twitter last night showing his messed up face with the caption, "Pretty sure I got hit by a car, but I have no memory of what happened... at all."
The next morning, Dick began to recall what went down and said he was biking home after drinking at a bar in Dublin -- when suddenly, he was being woken up on the side of the road by a cab driver.
Dick refused medical treatment ... but the next morning promised his followers he'd get checked out.
The reality star -- who won a $500k grand prize in 2007 -- swears he didn't just get into a drunken bar fight ... but not going to a hospital immediately after being run over by a car sounds pretty dumb.
