Hello. Has anyone else noticed things changing in the sky when you look sideways looking up? I mean when standing and looking up with the neck bent to one side a little. I do not know if it is the pain in my neck causing these strange images or they are always there but invisible with regular vision. I will investigate further , but for now i have noticed it on the days that i have a slight stiffness in my neck. These somewhat strange things look like a rainbow sometimes and just darker blue or purple bow in the sky. Thanks.
