Little sound like a bubble

First of all I have to say Thanks to all of You to make this connection here so pleasant, lovely and magic. I found here my nest, my home and family. Sometimes I cry feeling so grateful to live this unique and wonderful experience. Please forgive me for my English that is not good enough but im doing my best for you to get my message, intention and love, Thank you!
I want to ask you if some of you have been experience this particular thing. While I meditate and I get to a climax of connection with my inner nature suddenly I hear in the middle of my head just right there between my eyes, I assume is the Ajna Chakra, a little sound like a bubble making a subtle sound up, like clicking or something, like is related to orgasmic feelings similar to a sexual orgasm. That happen not just during meditation but when im aware of something profound, looking at the sunset, cooking or even during sex..
I would like to here some explanation of this, im fascinated with and notice that is increasing so fast. Also i start to see a blue purple light
that appear for seconds when i talk with friends or family....
Joy and Love for all of you.
