Dear Michael1719,
What you are experiencing may be floaters or a migraine. I would definitely recommend that you see an eyeMD to determine the cause. Let the doctor know whether you experience flashing lights with your eyes closed, a sudden change in the number of spots that you see, or a curtain coming down. You do not mention how long these lights appear.
