In the episode "Realm of Fear" , Geordi states that there have been 2 or 3 transporter accidents in the last 10 years. Is he including his own experience less than 2 months earlier?
To paraphrase"The Next Phase" episode recap, "While helping a Romulan science vessel, a transporter accident forces Geordi LaForge and Ro Laren slightly out of phase, causing them to become undetectable to everyone but each other. As a result, the crew thinks they are dead...."
If Geordi and Ro hadn't solved the mystery, they would have died from dehydration in just a few days, as they were unable to eat or drink in their phased state.
