I'm Eric. Long story short and simple,
1. This happens quite rarely, like once in a month: I have a headache, I can't sense nor see, there are sparkling dots that "attack" my vision (they are like the dots on TV when there's no signal... Something like that). But after the dots ebb away and I get my vision back, I feel much more energetic and positive, I feel powerful and my body feels like... There's electricity flowing through it. I don't know how to describe it (and English is not my main language) But it's like the sensation when my vibrations are raised, only that it's stronger. I have no idea what this is. I read some other posts that have similar experience like this but sadly none has the answer...
2. Sometimes after an event happened, I realize I actually have seen it in my dreams. This can happen thrice in a week. That one particular night when I was asleep, I felt my body vibrating very strong and... Then nothing happened, just the vibration and it disappeared. I woke up finding myself sweating.
3. This one started a week ago. I had a weird sensation on my forehead (center, above the eye brows), it's pulsating and beating like the heart/pulse. Then it stopped but it left a tingling sensation there on my forehead. I read about the 3rd eye things but this experience... It's only the tingling sensation and nothing else. I searched about this and it led me to the discovery of binaural beats on YouTube. I read the comments there and they said they felt the same sensation after meditating to the beats. And it might take some time to decalcify the pineal gland. I don't understand about the decalcifying thing; (I hope I can get an explanation about it here;)
What do you think I'm experiencing? Especially experience #1.
