Some symptoms are colors floating through the air, white walls looking like they have been painted with water colors (not as in a picture- just splotches and swirls of color). Some people see walls "breathing" or melting (I do not have this) Some see auras around bright lights, white or purple sparkles in the air, morphing of rocks and tree leaves into outlines of random animals or other things. Some see images inside of other images. Like a rock will look like it has an image of something else inside of it, for me it's animal faces or people faces. I do not get visual snow, which is a grainy look to the world. Visual snow is very common in hppd. Some people, including me, have trouble reading at times. Words get jumbled, turn colors, letters look different than they should and are hard to differentiate from other letters and tend to "pop" off the page. Some people get blurred vision that comes and goes. A typical symptom for every hppd sufferer is seeing after images when Iooking at a TV or Ipad and then looking away, especially at night. Other people see tracers when things are moving. The symptoms come and go. Sometimes I am fine for a couple of days and then one or more of the visuals will come back. Some people have depersonalization and derealization. Everything feels unreal and it's like they are watching life but not really participating in it. HPPD presents a bit differently for each person. On my bad hours or days I feel like I have taken acid and am "tripping". I am tired but will return to this section and try to make this into more of a list.
