Download a free audiobook version of Hallucinations and support TED-Ed's nonprofit mission: Check out our full book recommendation: A condition called Charles Bonnet Syndrome can cause blind patients to hallucinate scenes in vivid color. fMRI studies show that these hallucinations activate the same brain areas as sight areas that are not activated by imagination. Other hallucinations also involve the same brain areas as real sensory experiences. What's going on? Elizabeth Cox details the science of hallucinations. Lesson by Elizabeth Cox, directed by Nerdo

Interesting material, yes; clearly explained, yes. .. but the animations - are they helping to convey the information? Several commenters praised the animation, which, I take it, means they were spending quite a bit of their attention on them. Attention is a limited resource. Unless the visuals in a presentation, in this case animations, are directly linked to helping to illustrate/clarify a point, it's better to ditch them.

One time i was trying to go deep in meditation and i thought i sleep but i was awake, and I don't get any visuals that are more normal but i was hearing and controling a whole orchestra, i was hearing every instrument and i was able to focus on then individually, i never have heard this song that was playing, it feels like i was creating the sounds all at same time, it was beautiful

This happen to me when I was 5 I looked at my bed my mom was there she looked like a zombie. and I say boats and stuff that looked like they are put in with crayons in 2d and I was creeped out. I asked my sister what was happening and she said nothings wrong and I know that something was wrong. Next day I was back to normal but still was scared.

It's so scary to think that all things around me that I have always seen, could just disappear from my vision if I went blind (or just when I close my eyes, becauese I'm so used to seeing them and that's so big part of my life every day that I never think of seeing and that it's my brain, eyes and light working together.

One weird thing I thought was a hallucination was that one time I was at my cousins pool party, it was her birthday. I was in the pool, just there. And then, I saw a humanoid shadow, so I turned around, and no one was there. To this day, I wonder. Was it a hallucination. Or was someone really there?
