Imaginary friends? (serious answers only please)?

I don't have imaginary friends, never have...but I used to write to my journal daily so that I could document my life...I talk to myself a lot...and I once believed that I had a muse who inspired my creativity...I think I lost my muse though, because I'm no longer creative like I was. Honestly, whatever makes you happy makes you happy -- if people have a problem with your imaginary friends, just don't tell them about it! It's that simple! :)
