Switch Bug or intentional?

Made an account to hopefully get some answers as google is no help.

Picture me, casually mining stone and copper on level 20 some of the regular mines, and I find a ladder. I take the ladder and am transported into the pits of Skull Cavern hell (no, I think it was level 24 or 27). It was definitely the skull cavern it sent me to. I almost died. This happened twice, very similar both times.

Is this intentional and just very rare or is it a bug? My sister who plays on PC (for much longer than I) has never experienced that and as I said, google gave me nothing.

If it helps, I have reached the end of the regular mines and I have entered the skull cavern, but nowhere near level 24 or 27.

I want it to stop, it's very spooky.

I don't think that is intentional.

Where do you end up when you leave the skull cavern?

Back in the beginning of the regular mines, with the minecart and the elevator.

Are you sure it's the skull cavern?

What kind of monsters did you encounter?

If it was flying skulls, that's a dungeon floor in the regular mines. They show up randomly, like infested floors.
