I, for great periods of my life, constructed elaborate alternate imaginary lives too. I've done this from childhood right through to adulthood. I have always assumed it was normal.

Did it affect my reality? I suppose it served to concentrate my discontent. I suppose it affected my social health as I withdrew into the happier existence. As such, it may have prolonged feelings of depression or opression. Regardless. I honestly believe doing so saved my sanity.

I haven't done this for years. I wonder if that is owing to medication?
