In my experience, it is most often a case of "wherever I go, there I am". I have traveled to locations as diverse as the parking lot of a motel where I happened to be staying (an RTZ type experience), to a Venusian type of environment with landscapes ranging from rocky cliffs to ponds of molten metal - in which I was *very* grateful to be OOB

More typically, I find myself floating around earth-type environments, ranging from inside industrial/school type buildings which seem unending and full of people, to outdoors in thinly populated forest/prairie/mountain areas with the occasional dwelling, to dense city locations with lots of buildings, people, traffic, animals etc. Usually in all of these environments my own physical density is relatively quite low, and I float through walls, ceilings, floors, etc - anything solid - I am insubstantial and ghostlike.
Most people in these places are either unaware or indifferent to my presence, but usually if I try to touch them, my arm passes through their bodies, and they shiver as though they are uncomfortable by my touch, so I leave them alone for the most part. Usually however someone is able to recognize me (after I experiment at getting their attention for a bit) and we interact briefly. I can only remain in these locations for a limited period before being pulled back to my own physical location and body, or simply fading away into a dream pool.
I have tried to gain control over where I go, but this is still touch-and-go for me. I seem to migrate to different locations at random, although my vibrational frequency plays a role, in theory at least.
I hope this helps to shed a bit of insight.
