I've been seeing dark shadows and movement out of the corner of my eyes lately. It's happened before but not for a long time and it was at times when I had little insight into BP so don't know what kind of cycle I might have been in. Am I 'seeing things' or is this just a normal variation of life? Have any of you experienced this?

(sorry if the text size is too large or small, I've been having a hard time with this lately).
