Sounds like you didn't actually have a lucid. A dream about a lucid has happened many times to people, it sucks. :/ In my opinion nose pinch is best and easiest reality check. It's hard to say how to become in control if your watching yourself. Try to become first person then gain control? If you COULD do that, then you should have no problem! But it aint very easy.. So just keep doing reality checks and hope for a better dream scene! Hope I helped at all..!
