I think I did in childhood but in adulthood I haven't experienced any, I just figured i'd give the WILD a go, Couldn't really see the harm in trying to still the mind, I figure its abit like meditation your obviously not going to suceed if you never attempt to achieve it, and I figure it makes an impression on the mind of what to expect when and if it does happen. I'm sure theres more logical ways of a new comer that hasn't experienced anything LD related in years but I was just attempting to get used to it, having a go, I didn't think any harm would come from wanting to try.
