I was scavenging a house when a zombie walked through walls and attacked me. I had already been attacked before and I was lacking blood, though fortunately I had bandages on me. So the zombie attacked and I thought I could use my axe to fight him, but he made me bleed and I quickly fell into coma. I woke up one minute later to find myself laying on the ground, but UNDER the bed (or at least partially). I then tried to stand up, to move, anything, but I was stucked there. The only thing I could do was to look up and down, and I still could use my inventory and any other game function. But then I fell again into coma (I guess the zombie was still attacking me, or I was losing too much blood) and came back to consciousness five seconds later, but I was moving this time. Well, I couldn't control it, I slowly shifted through walls and objects in one direction, still unable to do anything, though I could use a bandage to stop my bleeding (which applied himself immediatly, without any animation). It continued like that for 30 seconds, falling into coma, coming back (sometimes in less that one second), and I finally decided to leave.
