Some of those drugs could cause hallucinations, and it could be (not say it is), drug-induced psychosis. Then again, it may not be that. I do have schizophrenia. I've seen countless of things that would make no sense whatsoever. Here's an example of a farily mild one (happened a few days ago):

I was walking the dog with my mum at night, and on the road was a reflection of the light from the streetlamp that had reflected off some surface and now was on the road. My mother did see this (she's not schizophrenic), so I know that part was real. As I kept walking, the light turned into more of an outlne of a human, with hands, a face, feet, legs, fingers, etc... . It stood up and moved around. Then, it sat down, glared at me, pointed a finger at me then lay down while still pointing. As I walked past it (using my mom and dog as a shield), it kept moving around, so I sped up and later slowed down and it had vanished.

I do have various thoughts about broadcasting and about people coming after me. I feel that my thoughts are being broadcasted to others, more specifically a group of people (believed to have seen them in hallucinations) that will come after me and hunt me down. I feel that other people know of this yet constantly hide it up whenever i'm around by acting all casual but really are watching me. They have electrical devices that are monitored by this group that help find exactly where i am. Some of these conspicious things are like if a crossing guard waves to people to come across, he's actually saying for them to cross because i'm in that direction. he wants to be conspicious so i don't feel more threatened and so i won't run off but i know he (and the others) can still hear my thoughts because they're routed through a large speaker where all of them can hear it.

i'm not too sure on insertion because they're very good at hiding things up. i know barcodes on items (i.e. tomatoes) can stick to your finger so it'll take your fingerprint. i think that if they can read my thoughts, they can also put things in. here is where i think the voices i hear really are them degrading me, commenting on things/people, commanding me to do things, etc... because they have very sophisticated technology, like the opposite of a brain-fixing machine.
