The holy spirit is just something the church's and religions made up, but If I was to come up with a correct meaning of what the holy spirit is it would be the below.
The holy spirit is the light the oneness consciousness and could also be known as the Akashic records.
I guess you would see the holy spirit when you become aware of the truths that there is not one God ruling over everyone, but you yourself are God along with everyone else, when you become light again with all other beings you become part of the holy spirit, you are the holy spirit like all within oneness.
