Usually occurs during an impromptu nap taken while watching television. The state of being half asleep but can still vaguely hear everything. Someone who is halfanapping is unable to distinguish whether what they are hearing is in the real world or imaginationland, and are therefore unable respond or react to what they hear until fully awake.
Sorry I missed your call, I was halfanapping and couldn't tell whether it was on TV or not
