fell asleep underground in a bed probably 5-8 blocks from the surface, woke up and had no clue where i was.

its a new world, awake for 2 days because i had no bed, stayed underground at night because my house wasnt finished. got the resources for a bed, my house wasnt finished yet, put my bed in an underground camp i made, 5-8 blocks from the surface. slept and it was ok until i woke up. woke up in a different place, dark, underground, small space. couldve been that i was underground or it was the 3rd day id been awake so the phantoms came.
