I can relate to almost all that you said.

Some of my more bizarre grandiose thoughts (which I only have while manic) are:

I am chosen by God. I have healing powers. I have authority over my prayers (what ever I pray will come true). I can cast out demons. I ooze sex; every man and woman who looks at me and wants me. I am going to be famous. I also find meaning in random things and believe they are signs that prove my psychic or spiritual connection (depending on the type of episode). That is all I can think of for now.
