Can someone 'in the know' explain this strange phenomena I've been experiencing recently

I can feel neurons firing in my head. The pattern varies, and so does the location, although this seems to occur more in the right side of my brain. Actually, I both feel 'it' and hear it to, it sounds like a clicking, electricity in my skull.

Here's an example:

I'm sitting on my sofa, smoking weed (this increases the effect) and watching some football (soccer to some). Now at this time my mind was messed up, I keep catching myself looking at footballers butts, worrying about my sexuality. I'd thought myself straight, but there's a worry that I'm not, and I'm thinking about this while looking at the tv.

*my mind is screwing with me*

then i have a revelation: 'how can i be gay when I was in love with....(un-named woman)!'

now as i get to the 'was' in that sentence(when I said 'was',i really meant 'am', but i forgot about this small fact of my life for 3 years, as i said i was disillusioned, messed up etc)....I feel a flash of lightning in my right pre-frontal cortex, with the epicentre smack in the middle of the lobe, and the feeling radiates out from it, covering my frontal lobe, radius about an inch and intensity lessening the further from the epicenter. I jump out of my seat clutching my head thinking 'what the hell was that? with a dull pain where the event occured, which subsides and is gone after about 10 seconds.

So i do a bit of research and find the right pre-frontal lobe to house emotions (is this true?) which matches my 'I'm in love' idea.

So there you are, that's the most vivid of these 'clicks' that i've been aware of. I believe it's a method of discovering truth through examining my own conciousness.

And are the feds gonna prod me with instruments like on war games? Can I use this to advance human understaning of the brain? Might as well contribute to civilisation while I'm here.

Anyhow, adios.

maybe this is some kind of epileptic precursor?

It's no type of epilepstic aura (precursor) if that's what you're concluding.

What do you know about epilepsy?
