There was a movie in the 1980's where the boy ened up in the hospital. When he woke up it was about 10 years later. The vurse who took care of him was really cute and flirty. There was also a robot that took care of him. The robot took him down the hall or maybe went with him down a hall and somehow they got to a blimp hanger where there was a UFO, airpod, spaceship, etc. He got into it and I remember it was above land and also below water and played played beach boys music.

Flight of the Navigator (1986)

It's The Navigator. The nurse is popular actress Sarah Jessica Parker. I love that movie! It's based in Florida - NASA, Orlando, Miami.
