Do I have HPPD?

  • Take note of how many of these apply to you, and how often.

    • I experience what appears like T.V. "static" projected over my vision during the day, or especially at night. 

    • Stationary objects appear to sway side to side, wave up and down or move

    • I see lights/colors that ring around the perimeters of objects

    • I see an image of an object when I look away from it.

    • When I read, I see white and/or black shadow "ghosted" images of the text.

    • I notice geometric patterns in my field of vision when my eye is either open or closed.

    • Spontaneously, an object will appear larger or smaller than it actually is. 

    • I see objects leaving trails behind them as they move, like long exposure photography.

    • I feel detached from my body, as if I am observing it from a distance. 

    • I experience the world as dream-like, alien and unreal.

  • Take note of how many of these apply to you, and how often. Because of these visuals, do you experience:

    • Difficulties concentrating

    • Difficulties seeing

    • Panic and anxiety

    • Confusion and overwhelm

    • Depression and sadness

    • A desire to isolate

    • Self-consciousness and embarrassment

    • Worry that your life will never be the same

Ask yourself two key questions.

Be reassured: these experiences are not uncommon, and many people recover. But if you find yourself agreeing with many of the bullet points, then you may wish to make sense of your experience through the label of Hallucinogen Persisting Perception Disorder (HPPD), and to begin planning your recovery from distress.
