This may take a little explaining - and it doesn't relate much to pick-up but more to NLP - but obviously your mind is a powerful tool. I was wondering if it is possible to make myself see things that arn't there at will. For example, if I was waiting in the doctor's office for an appointment, I could be snowboarding in a complete 5 sensory experience created by my mind and then jump back to reality. In a way I would almost have controlled schizophrenia. Is this possible? If so, how would you do it? I feel like it really is possible because its all in your mind so you mentally could force you mind to create it because remember - you don't see whats here, you see what your mind TELLS you is here. btw im not talking about day dreaming - im talking about a complete 5 sensory experience that feels exactly as if i was doing it in real life

You dont see whats in reality , you see a map of reality based on passed experiances. You could recreate that with NLP, but people do it all the time its called daydreaming. The intensity of your experiance could vary...

Build the experience.
Take, for example, an experience you really do a lot and enjoy, and gradually build up the experience, from your most powerful sensory experience (your "favored" one, or two.), and gradually explore that one to the full first, then gradually add the "lesser" ones,
e.g.
You like snowboarding, and your "preferred" sense is visual. Just as an example,
Start by visualizing the scenery, the snow, the board, the whole visual experience, and gradually, as the visual builds, start getting the kinestetic, the feeling of how the snow rolls under your board, the variety of snow, from the coarse to the finest powder, how your muscles take the shock etc.
Then start adding Sound, the auditory, by hearing the sound of the snow flowing, perhaps dampened by your cap or something like that, birds, etc.
And in this way, keep adding more sensory data, the smell and taste of cold air, and how it moves with your breath,

You can also use this as meditation, or to train your brain.
The more you do this sort of thing, say, if you have a hard time visualizing, the more you will train yourself to do it, and this will enrich your experience of the world, and also your understanding of other people.

Of course using it like that, would not start with visualizing, but perhaps auditory.

Hope it helps.
