Do you see a blue light sometimes when you are watching a blue-ray movie?

My mom and I just bought a blue ray player and we watched are first blue-ray Indiana jones and the kingdom of the crystal scull. I did not notice when we were watching the movie but my mom did. I went back after and saw a quick glimpse of the light at one scene the later at the end when they were in a chamber but I thought it might be part of the scene, a ray of light maybe. Thank you for your answer.
