Sorry Katie, I think I misunderstood what you were asking.
For me psychic ability is more about abilities than afflictions.
An ability to me is a gift that is in controlled use and of intentional benefit to the user.
Humans tend to have 'feelings', 'visions' and 'premonitions', but run away or hide from them. They try everything they can find to be 'cured' of what they often term
unnatural abilities, and would do anything not to be burdened by them. They treat them as an affliction.
This to me is not true psychic ability, which the owner has the knowledge, strength and ability to put to it's best and most beneficial use.
Many of those who call themselves humans do have what it takes to use these gifts and these are the unawakened kin that I spoke of previously.

We do have gatherings, but they are rare and usually signal a significant happening in our world. The rest of the time we often go many years without coming into contact with another of our kind.
Travelling... Well. Cars and Planes really.
When in the Astral it's kind of a mixture of the thinking and flying for short distances, I do enjoy skimming the ground and swirling round trees very much. It tickles.

For long distances I use the portals. That way is a lot like blinking. You close your eyes in one location and step through the portal, and when you open your eyes again you're somewhere completely different.
I must confess at this point that the Astral Realms the humans can get to are places I never go. Time out from their energies is vital to me and the Astral Realms can be completely human influence free if you know where to go.
Ooops I forgot.....
I am sorry DEA but I do not have any idea if it is easier as a formless being because I have nothing to compare it to.
