A childhood belief about imaginary friends

when i was 4 yrs old, i had an imaginery best friend.her name was saima. she only existed in my room.so around the house when i used to do something bad like bully my younger brother or break stuffs, i wud go to my room and tell saima what i did and she would tell me that it wasn't a good thing.she would also sometimes scold me for doing this or that. and i always listened to her.i used to think she was a real girl and i also knew how she looks like.but later when i was 12 yrs old i got to learn about this imaginery friends thing and then i got to know that saima was just an imagination of mine.now i know that though i was a naughty girl but i always knew about the goods and the bads...
