Wierd sensation in my head while high?

I will try to explain it the best I can. To clear things up, i smoke alot. And i have smoked for years without having this sensation so its a new feeling. Sometimes when i smoke i get this certain ''sensation' in my head. Im not even sure if its a sensation but thats the best word to explain it because i literally feel an image. Im not exagerating, when i say that when i get this 'sensation' i can sort of... feel the outline of an image. It's pretty wierd but imagine a baby bottle. Now imagine the bottle nipple that the bottle has where the liquids come out. Now imagine the bottle nipple on the side of your head as if it was attached to your head. The nipple is sticking out from your head so that there is this flexible nipple-like thing on your head. When i get this 'sensation' i feel like i have this nipple on the left side (only the left side) of my head and that someone/something is flicking it. I can very clearly feel that this nipple is being flicked? But i cant seem to make sense of what it happening. When i get this 'sensation', its not technically on my head, but in my brain. I dont know how i feel it on my brain and not my head but i know.
Few other things to note:
1. It started happening after trying to open my third eye
2. It only happens when im high
3. I have been in situations that people might believe dont exist, which is to say, i have telepathically talked to people without my consent
4. I promise im not crazy. If i were, i'd put myself in the nut house.
I honestly dont think anyone could explain or understand what in the world i am talking about but i thought i would give it a shot.
