Many of us who have IH experience frequent and disturbing amounts of microsleep attacks that interferes with our daily lives. It is a short state of unconsciousness where our brains fails to respond to sensory input. Usually that state lasts 30 seconds, but with IH brain, the state can be longer or person may experience multitude of them during the day.

I used to have them all the time before I was diagnosed and finally properly medicated years after that. It felt like I blinked and missed a chunk of class, a piece of dialogue, even part of the day due to having so many. I could not remember how I was suddenly one block away from the last moment I could recall, or how my friends were speaking gibberish that was unrelated to anything that had happened before.

In fact, it got so bad that I was kicked out of a goldsmith school due to being a hazard for everyone around me, and myself.

This is a dangerous state to be in, as your body might still be on automatic behavior and continue on without you really being on the wheel - so to speak. And sometimes, IH people have to take nap breaks so they wont crash on the car wheel too.

I personally can't drive due to my IH...but I hope this comic illustrates a little what microsleeps, which is one of many symptoms of not only IH but extreme sleep deprivation, is like.
