Can anyone help provide an explanation to 2 phenomena I expe

1) Say there is an apple in front of me. If I attempt to think about the apple consciously, I wouldn't be able to produce much thought. My focus would be corrected to an imaginary construct in my mind. This so-called imaginary construct appears consistently when consciously thinking. It is visually rectangular and has a rough texture. However, if I concentrate on removing the construct, I can think more freely.

2) Additionally, I'm not sure if there is a connection, but whenever I imagine a scene in my head there is uncontrollable swaying, turns, and angular movements that are out of my will. I simply can't keep an image fixed in a singular point of view.

I've had the phenomena for as long as I remember, and it only happens when I am conscious of my cognition. Have the above phenomena ever been documented?

Not that I know of. It seems like there could be physical/neurological, issues associated with this phenomenon. You could see your doctor and they might be able to refer you to someone.
