1. Do you have to use a headset for this to work?
I didn't use a headset the first time I tried, I got a massive headache...
2. Can you get brain damage from this?
Felt like I just did, haha
3. I would also like a bit of explanation of what this really does. Will this actually help me Lucid Dream? Sorry, this might be in the wrong catagory for this type of thing.
Thanks, been about 3hrs... a light headache is still there.
