This test will determine if you're getting enough sleep or if your mind has really lost it! The test consists of three parts: You'll be shown 12 photos in the first part. You'll be shown another 12 photos in the second part. You'll be shown 48 photos in the third part and asked if you saw them in the first part, the second part - or never saw them at all. When you have finished the third part, your results will be given to you.
