Paprika (2006):

"When a machine that allows therapists to enter their patients' dreams is stolen, all hell breaks loose. Only a young female therapist, Paprika, can stop it."

This magical tale centers on a revolutionary machine that allows scientists to enter and record a subject’s dream. After being stolen, a detective and brilliant therapist join forces to recover the device — before it falls into the hands of a “dream terrorist”. It really needs to be seen to be believed. There's a beautiful contrast here between dreams and mundane reality. Plus, many secrets the characters have are only expressed in dreams.

As the movie goes on, the dreams become darker and more surreal. People start talking nonsense and killing themselves. And eventually the nightmare visions infect reality. Only Paprika, who appears to be a happy-go-lucky therapist can stop them. Paprika's early scenes have a great sense of limitlessness and flight, in contrast to drab waking life, highlighting the theme of magical realism. Check it out, whenever you can!
