You have, through some magical or surgical process, obtained a second head. This second head and it's brain gives you advantage on perception checks and on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious. Also, you may have one of the heads awake at a time while sleeping during a long rest or on any other occasion.
Whether the second head carries a second personality is up to the DM's discretion.
