This usually occurs early in the morning, and the period you can be affected by it will extend the less sleep you got the previous night. During a Brainlapse, you forget where you were going, what you were doing and sometimes who you are.

Brainlapsing is usually accompanied by a halt in movement until the Brainlapse has passed.
