So, this has started about Wednesday, Thursday. Anyways, it was night time in MineCraft. I had a bed in the area I was in so I decided to sleep through the night (Like I usually do). As I got into the bed and the screen started fading purple, suddenly, I was out of the bed and had a heart gone. When I looked around, I noticed there was A Zombie. I quickly killed it but realized there was no way A Zombie could naturally spawn in there (The light in my house was definitely enough to keep monsters at bay). I tried it again, and this time a Skeleton popped me out of bed. Killing it, I decided to start a new server. I built it up, filled it with lights, and the first night I went to sleep there everything was fine. The night fallowing, I was attacked again by a (Laughing) Skeleton. I am thinking there is something wrong with my Minecraft game, but has anyone else gotten this problem? And if anyone had this problem, how do I fix it myself?
