Pineal gland or something else?

so when i have been in meditative states lately i feel a sort of inward pressure on my forehead a little above an imaginary line connecting my two eyeballs. i also hear/feel little clicks coming from that same spot. from the pictures i've seen it seems like the pineal is located more toward the center of the brain than in the frontal region. is my third eye opening or am i becoming delusional as my doc puts it? or is there something else going on? has anybody had this experience?
also a few nights ago i was just laying in bed with a completely clear mind when a sort of image came into my head of this place in the forest that i was considering going to for a couple of days, and i swear the most intense electrical shock ran from my forehead into the middle of my head. it only lasted like a half of a second but it made quite an impression on me. needless to say i think i will go to that spot. it was not unpleasant but very... shocking. i have only experienced this once.

any insight? thanks
