Has anyone ever had a ghost enter there body and speaks through you - well i have i would like to hear from?

other people who have experienced this - its is my grandmother on xmas eve 2005 i felt really funny and went to sit down and then i started talking exactly like her and acting like her - speaking to my dad which is her son - very spooky - it has happened several times know - i have ghosts in my place all the time but i know them they are my family - this is not a question as such but just curious to see if anyone else has experienced this thanks
