Yes!!! Months ago, probably June ish it wa really bad, was happening every day, I thought I was going crazy. I had an eye dr appt and asked him about it because I thought it was my eyes and se said my eyes looked fine. I brought it up to my psychiatrist and he didn't think much of it. Then I was reading about bipolar and hallucinations and brought it up to my family dr and I feel like this is what it is. It's exactly as you describe. I feel like I see someone walking by me or one of my cats is at my feet, or even a few times I get freaked out about something going by me fast and look and nothing is there. It freaks me out.
