An it harm none, do as ye will.
As you make your way into Smearland and you begin to see exactly what is possible, you will be tempted to try a few things out.
I'm not going to tell you what you should and shouldn't try if/when you find yourself able to navigate at will in 5 dimensions. I have no authority to do so.
I will tell you that the Universe has absolutely no problem kicking your ass if you get too cocky or arrogant, or do something you know you shouldn't be doing. It seems to be a self-correcting system that is limited only by its input. Most of us can't escape the input from our conscience. And arrogance alters our expectations of ourselves and those around us.
Neural networks are a good analogy. Every time you activate a particular node, you change the likelihood that that same node will fire (pass on a signal) the next time it, or the nodes surrounding it, are activated. One activation may also change the level of activation that is necessary for it to pass on that signal the next time. Navigation in Smearland has a whole lot to do with what is going on in your brain. Neurons activating and firing are the sources of chemicals, and chemicals are the (ultimately) the sources of subatmoic particles. I'm grossly oversimplifying this right now - we haven't even begun to talk about the mechanisms of memory, attention, emotions, etc. - but trust me when I say that each action alters the potentials associated with future action.
I highly recommend educating yourself - psychology and neuroscience being more important than physics at this point. The paradigm of 5-dimensional existence is so new that many, if not all, of our assumptions about the ways things are can be questioned. It is largely from these assumptions that we derive ethics. I'm not saying that you should not be guided by an ethical or moral code of some kind; I'm saying that I am not able to tell you which one is best and why. That you will have to decide for yourself based on reason and experience.
And if you are in Smearland and you begin to feel the pull of the 'save the cheerleader, save the world' mentality, might I highly recommend Robin Wood's book When, Why ...If.
