I'm a 15 year old male I am exremely unstressed I eat healthily and get plenty of exercise I live in a rural environment with clean air. A few years ago I began having "episodes" the doctors were baffled and had no conclusion as to why they were occurring it was never diagnosed and then one day it stopped for no apparent reason but now two years later I have begun having severe prolonged horrific hallucinations and some other shorter ones that mess with my mind I am dumbfounded and need advice on how to stop them and or why they are occurring

What kind of tests have been done?

It's time to go back to the doctor, they need to do tests, I'd start with a CT scan of your brain.

We really can't give you a diagnosis, there's no way for us to know what's going on so there's no way to advise how to stop it.

You really need a doctor for this and make sure that you're sent to specialists. This is your health, don't take "we have no idea" for an answer. Someone does and it's their job to find that someone and help you.

Let us know how it goes and good luck.

Have you been to a mental health specialist that could test for imbalances? The brain is a complicated machine, and any number of things can cause any number of problems. Sometimes something as simple as too much or too little of a certain mineral can have unexpected results.

Getting a CT scan would also be a good idea. While a chemical or mineral imbalance is possible, so is something more serious, like a tumor or other blockage.

I used to live in ireland and my specialist took a special interest in my case, he was convinced of epilepsy and ran countless to test for it and other such things but found nothing out he did start to suspect growth isues. When I moved to the u.s. somehow my medical records never came with me but my current family doctor believes it is caused by pressure on my brain and recommended a ct and/or a mri. I am terrified of both of those things but I am also terrified of what happens if they don't happen
Do you really think I should look further into it

Absolutely. If it IS caused by pressure in your brain, then letting it go may cause more serious problems. It's never a good idea to play with the health of your brain.
