Hi Satman,
I'm so sorry to hear of your new diagnosis. Like it was stated before, can it be treated with radiation?
As far a hallucinations go, my daughter, Chelsea, experienced this also. It freaked me out a little but I had to go along with it until they stopped. One night while in ICU she sat straight up and started hitting at me as she was slapping black widows off of my shirt. She started screaming and brushing them off her bed and her blankets. Turns out the the meds she was on have this side effect. She was on everything (meds) at the time but the one that seemed to trigger this reaction on hallucinations was too much 'emetics' (spelling). She was on several at the same time to control vomitting due to hydrocephalus. The one that seemed to work best for her, yet in high doses caused hallucinations, was compezine. Percodan gave her nightmares. She was also in surgery for a long time. First one 16 hours, second on 2 weeks later was 15 hours. I'm sure the anesthsia for that long has to do something to the mind.
I sure hope you can escape the knife this time.
With all my best,
Michelle
