What's it like to breath a dense atmosphere?

Assuming that by "dense" you mean "has higher oxygen pressure than sea level on Earth", I think you'll end up feeling a bit more active and energetic as the oxygen pressure (the % of O2 in the air multiplied by the atmospheric pressure) is higher and you can breathe more of it in per breath. However, if the atmospheric pressure is also high (above a few atms), you need to watch out for narcosis and poisoning from the buffer gases (esp. Nitrogen). Also, slower winds will do more damage in a dense atmosphere, since more air is being moved around - however, it's harder to get strong winds for the same reason. Higher atmospheric density possibly also does things to the speed of sound too.
A thin atmosphere is exactly like breathing air at high altitude - less O2, which leads to altitude sickness and requires a period of acclimatisation. If the O2 pressure is low enough (to about 0.1), oxygen starvation is very likely.

What would an visitor to a dense world (by which I mean Traveller UWP dense atmosphere) need to do to stop narcosis - a period of time in a oxygen tent? Or would they eventually aclimatise?
As to thin - is thin breathable without assistance after aclimatisation (i.e. like at 3500-4000 meters (Materhorn base)) and v.thin with assistance, as in sky diver gear?

Nitrogen narcosis is only a problem if the atm pressure is high enough - about 3+ atms I think, with standard O2 pressure. So normal Dense atmospheres don't have that problem, Type D (Dense, HIgh) would at the surface though.
Thin should be breathable after acclimatisation. Very Thin needs O2 masks and stuff.
