Hi,
Welcome to our community.
I don't have much experience with hallun...s but I do believe both of you.
Maybe our moderators will move your plea for help to a better place for advice. I'm sure he's not the only one with this condition.
I do know August it too far away for your problem to go undiagnosed and uncontrolled. If these episodes are getting worse you may need restraints or knock out meds, injectables, available to you so he doesn't injure himself or someone else accidentally.
You need to get him a firm diagnosis so you can get him treatment and prepare for these episodes.
Chemicals of some kind introduced into his body in some way could cause these symptoms.
I would think a good psychological evaluation wouldn't hurt. Could explain a lot about the hall...s.
Hope you find answers soon.
