Fast Moving White Smoke And Lights?

Last night I had a weird experience and I can't make out if it was a good or bad one.

I went to bed feeling quite tired but couldn't sleep, after about ¾ of an hour, even though my eyes were closed, I experienced like a flashing of light. We live very rural and have no outside lights or street lights. When I opened my eyes I thought I was looking at my chandelier on the ceiling, then realised it couldn't be as the chandelier is at the foot of the bed not above the top of the bed. As I tried to make out this "reflection/double vision/whatever it was", I noticed it was changing shape. What I was seeing was like white/grey smoke, constantly moving, really fast and tiny white lights, so parts of it looked like snow in a snow storm, the "smoke" was a big area, hovering over my bed. It became quite dense and some of the tiny lights were other colours, reds and purples I think and all moving really fast like a puff of smoke would if exposed to a draft. At this point I thought MY HOUSE COULD BE ON FIRE AND I AM JUST WATCHING IT! But in those few seconds of thinking that, I couldn't actually believe it. I had left my 19 years old son watching TV and had my mobile by my bed, I phoned him and asked him to come to my room and not to put the light on as he came in. Well he thought that was a bit creepy but after coaxing he came in, unfortunately with his phone light on and with that light the "smokey things with lights" couldn't be seen. He sat on the bed next to me and I turned his phone off and I just said "watch". I saw the smoke/lights again and he said "what the hell is that!" There, I could have explained my seeing this vision because some could say I was half asleep etc, or because I have been suffering from an eye infection and my vision was a bit blurred still or because I am going through a really tough time in my life and may be susceptible to visions/hallucinations etc, but I can't explain my son seeing exactly the same thing as me, I asked him to describe what he could see BEFORE I told him what I could see and he said "it's like the northern lights/stars in smoke swishing around above your bed." We watched for a while, as it moved around and experimented by turning the light on and off, we could just make it out with a light on at that point. Eventually it died down and the smoke seemed to disappear, as I went to sleep my ceiling looked like the night sky, the tiny lights still there, like the stars. I think the smoke experience lasted about an hour though!

This morning it dawned on me that I should have tried to take photo with the phone, if this ever happens again I will. I have also had to message my son from work and ask him did that really happen, he just messaged back "yes is did"!
