hamster wants to bury my hand in her bedding now

hello! today was a huge milestone, i have been in the taming process for2 weeks after getting my new hamster and she finally crawled onto my hand, without treats, and even let me lift her up! seems like she was extremely curious.

we played a lot, she crawled and ran up and down my arms sniffing me. however, now that whenever i put my hand in her enclosure, she (lightly) starts biting (more akin to grabbing) my finger with her teeth and is attempting to drag me to a safe burrowing spot, then she tries to bury my huge hand in her bedding! could this be explained? i am happy this happened but its a bit silly when she constantly follows my hand around!
