My dad, brother and I were looking at a little plot of land somewhere in Africa to construct a little building to use as a small store. We found, a little ways down a road, there was already a building the size we needed it (about 12’x20′) We approached it and opened the door. The place was being used more or less like a shed and was full of clutter. My dad got busy taking some measurements while I looked around. There were closets in all four corners. I looked straight up and the ceiling had no attic and I could see a vent/chimney straight above me. I noticed how one end of the place was sort of partitioned off, kind of as a separate room with a big window on that side. My mom joined us & was sitting in that side room chatting on the phone. Straight ahead of me to the right of the front door was a large picture window with closed blinds which made me realize this was probably originally built as a house. I went forward & drew the blinds and saw the sky was getting dark with clouds and it looked like it might rain soon. Then I saw a herd of yaks (or some animal like that) and I felt like the storm was probably agitating them. Suddenly one of charged the picture window and broke a large hole through it and sort of bounced back and ran off. Before we could really grasp what was happening a pig seemed to come from out of no where and charged the window at such a high speed it broke through the remaining glass on a B-line toward the end window. It knocked my mom through the window and she and pig landed on the ground outside. We rushed out to tend to my mom and she seemed OK. I was so angry at the pig I grabbed it by the sides and flung as far away as I could. I remember the gushy feeling of its fatty sides in my hands.
