Thanks Mes Tarrant I'm gonna see about picking one up.
And thanks for the other help but it doesnt work for me.
Ignoring is impossible because it's not comfortable, so its too distracting to ignore. Besides, I can't concentrate on 'nothing' when i'm currently seeing something.
It only happens in meditation when i'm starting and i'm not tired.
I find thats the only thing that works because if i'm not sleepy then my eyes open when i'm thinking vivid thoughts.
