Yes, that sounds very much like you've already started to have Psy-Vision activated. That's very good.
When one has learned to perceive the «fabrics» of the Astral, then Auras, Energies and Beings look like transparent gray facets, but then colors, shapes, down to specific details appear. Then you will be able to perceive other Astral properties: tastes, sounds, odors, temperature, pressure, etc.
What you have seen is only a small part of the great variety of possibilities. Continue to move confidently towards activating and strengthening your Astral Sensors. Remember that it is not enough to open these Small Chakras, it is important to strengthen them, as well as to learn how to use them correctly, that you were able to correctly interpret Astral signals and even influence them. Best of luck to you.
