I cannot look at a video of the ocean or the open sky

Okay - I am not afraid to be in the ocean, or to be up in the air, but I cannot look at a video of the ocean or the open sky. I get anxious and have to close my eyes. It is weird. It's just the video or photo of such things because I love the water and have been up in planes, hot air balloons and didn't have the same feeling. I HATE IMAX theatre scenic pics with ocean waves, and pics like up in the air on a tower, etc.
