Question on throat chakra

Hey everyone!

I often hear of people talking of the heart chakra and the third eye as well as the crown chakra opening. But what of the throat chakra? What happens when that opens?

I ask because for some years now, I have been experiencing things that seem to align with the area of communication. For example, I have seen archangel Gabriel after coming out of meditation (I heard her name telepathically and repeatedly just days before this encounter). Recently, while meditating, I began to see very light clear blue all around me, but the same color as my signature down below but a little lighter, all around me. There have been other, more practical, daily life things that seem to happen, but I was just wondering what happens to others or if this has happened to others.
