It's a controlled lucid dreaming project, if you read the website, it tells you that.

"This involves waiting until the subject becomes so tired that she is able to almost instantly fall into a dream type of state. Before the subject falls asleep the conductor will usually instruct the dreamer on what he wants the subject to try and experience. The conductor then wakes the subject and she reports her dreams. The I.D.A technique is repeated multiple times and is documented via video & written notes."
