Read a text about lucid dreams.

Dreams can range from the mundane to the horrifying, but lucid dreaming, during which
dreamers are aware they are dreaming, is a mysterious category all to itself. Though lucid

control their dreams at will; they may change the details or plot, or they may switch to a
