A childhood belief about imaginary friends

At the age of around 4, I had 3 imaginery friends, i never created them they just appeared and to they were real- at the time anyway because they werent what u would expect. One was a multi coloured pyjama jumpsuit, the jumpsuit or jumpsuit as i called him, would float around in the air, like someone was wearing it but there was no body, head etc he was a great friend. The others were baby and sooty, sooty from the kids program, he was my right hand man and baby, was a floating baby, i wasnt too keen on baby. When my older sister used to walk in the room and see me playing and talking to them, which to her was thin air she would run out scared and screaming. We had to move house and from that day on, when asked where my friends were, i would say theyve gone to scotland to be friends with someone else. Im 25 now and lookin back i guess i sort of miss them
