Sorry to hear about your sick snake. When I hear of 'disorientation' the first thing I suspect is something toxic. Have you recently sprayed any ant killer / bug killer / plant spray in the house? Are there any toxic fumes, gasoline, strong cleaners, etc...? I used to try to keep pet tarantulas at work and they kept dying. I suspect it was the facility guy spraying bug killer around the building on a regular basis that did them in.
