Sounds alot like illusion.
Delusion would be creating your own illusion of reaity.
As in being delusional
I think people choose to be delusional as a form of escape from reality.
Thus my saying ignorance is bliss.
This is a highly dysfunctional way of thinking.
And far too common.
My delusion is I have to keep reminding myself that my opinion is not what people want to hear! I have tried very hard little by little over the years to humble myself. hhahahahhahha So, exactly my ignorance makes me happy at times until I confront myself and say hey thats not right, just let it go! It is a very highly dysfunctional ideology that I think is abundant in they eyes of every creature. I have 2 doves that live in my garden, I feed them dried corn and hemp seeds. They other day, they were eating and a pigeon landed to eat too, instantly one of my doves puffed up and made Beep Beep sound claiming his territory! hahahhahahahha The 2 think this is their land and they own me! ahhahhahah Thank you always!
