Creepy Mysterious Minecraft Pocket Edition World?

Okay so I tried to use a map for the first time on MCPE and I did it wrong. I opened MCPE and scrolled down through my worlds to find a new world at the bottom. The name was blank. It said the last time I used it (which was never) was "Long Ago". This honestly creeped me TF out. Before I loaded up the world to investigate further, I went into edit mode. The seed was 0. This creeped me out even more, but I still loaded up the world. I spawned in the ocean right next to a huge chunk of land. Since I was in creative, I flew around the world. I was so creeped out, that I exited the world and deleted it. What does this mean?

How to stop redstone flashing in minecraft?

I play minecraft PE and recently started using redstone, so I decided to use it for the lights in my building that was already built, using a lever to turn them on and off. I have tunnels going underneath the building carrying the redstone and the repeaters. For one set of lights, I have four lights operated from the one lever, I basically had two and two and joined them together. But when they are turned off, two of them flash every so often, I've tried everything to stop it but it's not working. I've heard of having a 3 block height above the redstone, which I did, but it didn't help. Another set of four lights also acted funny, two of them flashed while switched on, but I fixed that by just adjusting a repeater, I did that with the other one but it didn't work.
