So, Yesterday I was playing some pure vanilla minecraft, and decided to use the seed ModsAreBae I was spawned Next to a ravine, and a village. After about 45 minutes of basing there, I noticed there were always zombies groaning no matter the time of day... So I turned on subtitles and began digging downards. Lo and Behold there was a dungeon not 5 blocks under the surface!! Then after i decided that I no longer was going to use the world because of my dislike for vanilla, I decided to go into spectator and check under the village... Not only did I see the Dungeon i had previously mentioned, but there was another one about 50 blocks underneath the first one!
