There have been similar incidents reported all over the ship. Feelings of déjà vu. I had a premonition Geordi was going to come into Sickbay. A few seconds later, he did, with the symptoms of an ear infection. I was going to run the standard tests but somehow I had a feeling that they would turn out negative. So I ran an optical diagnostic which traced the problem to Geordi’s VISOR. His dizziness is being caused by a phase shift in his visual recptors. It’s causing him to see images that aren’t there.
