First of all, what do you mean by "sent to a.... world?" im assuming you travled to the snowy world? By worlds you mean biomes? If thats what you mean (like forest biome, snowy biome, ocean biome.) then maybe you could try dying, and then respawn where your base/world is. Or, if you have a bed with you and have reset your spawn point, open your world in 'settings' to LAN. From there, you can enable cheating, and choose to fly around. It might take a while, but you can find your home. Good luck!
