Keep working at it until you get that haze in the room that is clearly not the smoke, and opening your eyes right up does not interrupt it. As time passes you will even be able to move around a bit without interrupting it. You sound like you are making progress, though. Are you getting any kind of a falling or sliding feeling yet?
That’s how it started for me as well. As your ‘magick mucles’ and astral abilities sharpen those images become much clearer. Again, that is a great sign that you are making some kind of contact/connection. Now you know you are being heard, and you are ready to make the exchange a two way street.
That does not happen commonly, unless you are able to go for a full manifestation. I have gotten visuals, smell, images and some sound, but no full voice communication, no touch and not the ‘standing in the room talking with you’ experiences some have, so I can’t really help you there.
You are not going to, either. You don’t see the images literally on a scrying surface, at least not like a reflection. The black surface is basically acting as a blank canvas for things to paint astral visions with, or as a manifestation base. When you see something in the mirror you will know, because it is a lot more intense then seeing a wild reflection. Reflective visuals are usually literal smoke and mirrors. Good job with the TV screen, though. Tablets also work, a lake on a new moon, etc…
