Sparkling Lights
That simply means you are Awakening,
and your perception is expanding and shifting,
and that your angel and the rest of them you call is/are letting you know they there for you.

What sparks I see sometimes are kind of golden. It's like seeing tiny stars at the corner of my eyes.
The key to seeing the whole form if you want to is simply by tuning in,
after fully opening up to Divine consciousness or true Spiritual Awakening.

Keep on working on your Third Eye.
