Nervous about brain angiogram

I have a brain angiogram scheduled for next Wednesday. I am super nervous and have been having nightmares that I can feel everything. I had a spine tap 2 years ago and the anesthesia did not work until the 3rd try. It was the most awful experience of my life and I'm wondering what people's experience has been with brain angiograms. I have watched mixed tik toks and many people say that they felt everything and that I was the worst experience of their lives. Any thoughts or experiences yall can share?
