Time Travel & Slavery

There is a book called "Kindred" by Octavia Butler that is about a black woman from 1970's who time travel to the 1800's slavery past, where she is made a slave. She manages to come back, but her arm get stuck in a wall and has to be cut off. This is one of my fears of time travel, to get stuck in a bad past or to materialize with part of me inside something else.
