Sever Force

Disconnecting from the Force was a state of being achieved by Luke Skywalker during his exile on Ahch-To. It was far more difficult than using the Force, so much that Skywalker had to train for years to succeed. It is, however, impossible to cut off completely from the Force, as it still tried to reach Luke through dreams and even sometimes reached him when he was awake, despite his efforts, offering messages or warning.
