I saw the above question just now and I wanted to get my answer down. I’ll just get right to the point: yes, Phasing and Astral Traveling are the same thing. They’re synonyms. Meaning that they’re different words we use to describe the same thing.

There are other words that you’ll see people use to describe Astral Traveling, such as:

Phasing
Astral Travel
Astral Projection
Etheric Projection
Out of Body Experience
Lucid Dreaming
Remote Viewing
Projection
WILD
DEILD
MILD (basically any of those -ILD techniques)
Dreaming

Doing any of those above labels will take you to the same place (the non-physical) where you can do the same things.
“Dreaming” would be the only one from that list that is slightly different from the others. The other labels describe an event where you’re Conscious and Aware that you’re in the non-physical… dreaming denotes that you’re not aware that you’re in the non-physical. That’s the only difference between a dream and the rest of those labels.

In the end, I like to simply call what we experience a “Projection”. Mostly because if someone was to ask me “Was what I experienced an astral projection?” and I answer saying that it was probably a lucid dream, then immediately the individual asking the question feels like they failed because they didn’t have an “astral projection”. They didn’t do what they originally set out to do. It has a very negative connotation towards it. Whereby if I just say that, yes, they had a Projection, then it has a more positive influence upon them. They succeeded! And really, they DID succeed at what they wanted… which is to become aware while being non-physical.

I never worry about if I’m lucid or astrally aware in the non-physical. I simply ask myself, “was I conscious and aware while having a non-physical experience?”, and if the answer is YES, then I’m happy. Even if I didn’t, a dream awareness experience is still highly valuable to me.
