Corrupter Null

I was recording a gameplay of minecraft for my channel on my PS3.I have not updated minecraft so it is in Version T55.I used the seed GrannyHorror as the new game came out so I decided to create the her house in minecraft it was al going well.Whwn I closed minecraft AFTER SAVING,I was write at the beginning and there were holes which lokked like someone blew them up with TNT.In some holes,there was coming some sort of light like when you put a torch but there were none there.I entered the hole and broke 1 block and it all became normal I was frightened.After that I went to edit my recording but my Editor was again and again saying that the file was corrupt.I had recorded gameplays before but it never said this.Then I opened minecraft but there was no Granny world.I went to my Save Data Utility and there the last world was corrupted then my PS3 started to lag.My controller sometimes did not work.I took out my disc and it all was fine.This is what i saw.I drew a picture of him on paint.His smile also came on a sign in the hole.
