Am I losing my mind

I shot this photograph at my home at around sunset. As I was passing through one of the rooms , I noticed my shadow forming upon the curtain . This was not good enough. Then I tried to juxtapose my head shadow with the window curtain's shadow . This gave an illusory feeling as If my head is expanding . There can be multiple interpretations to it, but the one which I find the most suitable is the one in which I'm asking whether I can control my mind or is it the other way around ?
