This movie is from the 50's or 60's. A spaceship is under the sand in a vacant lot near a residential neighborhood. Whenever a person walks on the sand in this lot, music plays and the people sink in the sand. The aliens look like tall goons who all run in unison. I can't remembr anything else about the movie but that it terrorized me as a child and I continue having dreams about it to this day. Help me find the movie title. Thank you!:)
