10 years ago I went to one of our family frnds place with my parents n siblings just randomly when something had just happened 5 mins. ago. We saw their condition n could tell something unusual had happened. It happened to their 4 sons, 7-16 years olds when they were at home n their parents had left to buy some groceries. According to them, something jumped in from the window n started growing right infront of them n turned into a big monkey. It started running after them in different rooms trying to attack, eventually doors got locked automatically. Suddenly their parents came back n rang the door bell n that thing just disappeared.
We would probably have never believed it but when we saw the marks on the shirt of their 10 year old son, I was totally speechless. There were small cut marks on his pocket which he said, that thing tried to grab his heart with its big nails.
They changed that apartment within days. Later on, it was confirmed by the previous tenants, who we knew as well that, thats y they had left that apartment but never told anyone the real reason.
