Minecraft Pe is great, but there are glitches and after a while (while I am playing) it exits me out. Sometimes I die in survival and then it says I am still alive. I also sometimes have nightmares because it is sooo intense. Like I am sleeping, but I feel like I am fighting mobs. I would suggest to know what you are doing before you play on survival.
