Actually, Adderall could very, very easily be causing this. In the same vein of the guy who had CO poisoning, there was a man who was paranoid about drones doing surveillance on him.

It seems like it could be in parallel to your situation. I highly recommend having someone evaluating your dosage, as well as whether it's an adverse effect of the Adderall itself.
