Roki sleep walking? Or has he just gone nuts?

One contestant from one of the previous BBA shows once said that if you are not careful, time in the Big Brother House can make you go crazy. I’m beginning to find the truth in this. It’s either that or this guy has just lost it.

Roki woke up and walked out to the yard, in his underwear despite shaking due to the cold. I would understand if he spent some seconds there and went back into the house, but no. He just stood there for quite some time, two minutes to be precise. Just staring and shivering.

Really weird. I hope he was sleep walking. Take a look at the video.
