Bubbles And Visions

Several months ago while sitting in my backyard I started seeing what looks like transparent bubbles anywhere I look in the sky. It doesn't matter if the sky is clear blue, cloudy or over cast. If I look up there and focus, they are there every time. They seem to always be moving. They are transparent with a slightly darker outer circle and in the center floating in each one is what looks like a black spot or what I think is a small cloud. Some are moving alone and some are in two's or three side by side. They are always floating above me never so close to me to touch. Has anyone else seen these? What are they? I have also been seeing what I have heard described as a vision? Once again I am in my back yard and will all of a sudden see what looks like a film strip of a movie pop up in front of my face. There is always a great deal of detail that I can recall from what I have seen. It is also a moving color picture. It only last a minute and poof it's gone. It's always about someone I know. Never a still picture. It's like watching a very short movie. Anyone else have this happen? Is it a vision of coming events? Some have got to be of past events because I know one person passed on several years ago. All though I would welcome it if I am physic. I would like to know if I'm just plane nuts. Just in case your wondering I have had my eyes checked in great detail and have gotten new glasses. I have also had a brain scan done. Every test the doctors have done is normal. Anyone know what's happening to me?
