Difficult to notice people

I mean this less in the "wah why won't people pay attention to me" and more in a literal sense. People don't notice I'm there or forget I'm there and are startled when they do see me because they didn't see me approach. And I know I'm not the only one this happens to. I know some signs and aspects are supposed to have "presence". Is there such thing as the opposite?

Do you have Neptune aspecting your ascendant?

And moons position might have an effect as well

Planets in the water houses

I was thinking that, too: Aspects to Neptune, or Neptune in your first house. Moon placement as well. Also I could see a sun placement in the 12th house producing that sort of quality...

Also, Pisces people can be so filled with the universal energy of the "other" and "collective" that they can blend quite well and seem to dissolve into everything. My Pisces friends (and I have my moon in Pisces) tend to be very light on their feet, and have a "light" energy. I realize that's a generalization, but...food for thought.

Neat question.

When i was younger i had the impression that people get bored of me ,one day i realised that it was me that was getting bored often of the others and when that happened i was taking my distance...so im telling that maybe its you that wants to be unseen for your own reasons.

Too much Capricorn or Saturn in the chart maybe

Or lack of Leo/Sun and Aquarius/Uranus in the chart

I am the same but don't mind it because planets in Cancer. This depends on rising sign too. What is your rising sign?

Sun/Moon in 12th.
Pices/Neptune dominate. Post your chart or tell what's in it if you don't mind.
