I know what you mean. When I was manic, I posted on Facebook constantly, but a lot of what I was posting was very poetic. My friend who didn't know I was manic at the time told me she thought I was just experimenting with a new way of posting, like a new art form. Also while manic, I felt how everything was connected and I thought the world was going to end soon and I was going to play a very special role, a la the book of Revelations. Deluded! But it felt magnificent.
Also, in the hospital, I tried all kinds of sneaky ways not to take my medicine, like hiding it under my tongue or discreetly spitting it back into the paper cup. So then I was given a shot on my rear end, but I was fighting and screaming. I didn't like taking it because I read One Flew Over the Cuckoo's Nest, and the nurse we had was always in a really sour mood. When I asked her what the meds were for, she said they would "clear your thoughts." I thought she was going to brainwash me.
So my ideas weren't all that brilliant, but they were very exciting!
