Enter the Microscopic Dimension

I have often liked to envision what it must be like at smaller scales of our world. It has been kind of mind boggling, to say the least. Because in doing so, I have assumed we would still be just as we are right now, except smaller. That is, we would still have self awareness, consciousness, and all of the things that go along with the human mind! This is not possible, of course, because it is not possible for something small, such as an ant, to have the such abilities. Or would it? How small can something get and still have these abilities? How small could a brain get while still having the same level of function as our own? It may be seem simple... for me, though, I still have my doubts. I mean, perhaps it is in some way, theoretically achievable in nature.
Would microscopic life, still possibly have senses such as ours? And, if so, then this would be truly astonishing; as it would mean that life at the microscopic level can actually explore its environments much like we do.
Anyhow, here's something that I like to ponder some times. Imagine actually being so small, as to where you can wander around and are aware of microscopic features of the world to which we cannot possibly perceive. In fact, how about this: wouldn't it be neat if in the future, someone could analyze microscopic features of our world, and then make the microscopic realm virtually come to life? One idea of mine would be to actually go ahead and scan something; a "microscape", then make a 3d visualization of it. In other words, make a topographical map of it. Or even make it into a virtual reality. Then we could best imagine what the microscopic realm is like. Then, after all is said and done, it could be like playing video games for an excessive amount of time. You are in your own world, and then once you stop, you feel, well- "schizophrenic". Then it would potentially be astonishing once you entered back into the normal world. Then, once you looked through a microscope, you would be like, "I've been there before". My idea would be to achieve this through the use of technology akin to 3d printing. Although if we were to use a 3d printer, we would most likely need one far larger than the ones currently available. It's called thinking out of the box. I want to be able to be closer to the world that is hidden from our view, even the quantum world. We will be then be able to understand how the world works. Or will we? Imagine this: experiencing atoms as if they were not just in nanometers. As if they were many, many, times larger. So large in fact, that we would be aware of their presence just by our unaided senses! With us on a level that is microscopic enough, they might be like powder, for example. We would start to resolve them. And what would pressure, temperature, and other factors have on us at such a small scale? Don't take this as crazy;
There may be another realm in which this might just be the case. You never know. In our universe alone, the atomic scale is incredibly tiny. And we are relatively giany.  However, in another realm, or "universe", atoms could in fact be far larger. People might not be 10^100x bigger than atoms. They might be 10^5x bigger. We have no chance of ever seeing anything that small in our own little world. Most everything that's microscopic is intangible to us. More like this is on the way.
