No you would not be wasting anyone's time with this. I don't wish to sound hurtful but as you have asked, it is not normal - and you are aware of this.

As a bipolar person prone to bouts of mania my own delusions experienced are primary those of grandeur. I once actually thought I was a world class outdoor adventurer - even though I knew that was unlikely. But I imagined it all the same. I did some pretty stupid things and took some pretty extreme risks and chances owing to this belief. I was damn lucky I never hurt myself or worse. The thing was, in the back of my head I just knew this couldn't be real. I should have acted on that gut feeling and gotten help not continue to behave according to the wild belief I was some National Geographic Calibre adventurer. What a disaster it could have been.

Listen then to your own gut feeling and find someone to talk to about this. A good start is your family doctor. He/she will help find you some referrals and resources from there.
