It's a tricky one.

Because so many people are so physical-reality-focused, they will judge you by what they perceive of you and your life through their own physical senses. And in doing so, they will (as you point out) keep dragging you back into your current reality instead of allowing you to be free to enjoy your vision and its subsequent physical manifestation.

The funny thing is that physical reality lags vibrational reality by a long, long way. This is because it takes a thought to have condensed considerably in order for a physical manifestation of it to be perceptible to others. Abraham say that 99% of any manifestation is complete before it condenses enough to be perceptible to others in physical reality.

So you get people telling you that something doesn't exist until they physically perceive it. But they're wrong :) If it exists for you (even as a thought), it exists.

The upshot of this is that anything you see manifested physically is really looking into the past (at how your vibrational reality has been) and not the present...the present is the vibrational reality as it is now (in your thoughts) that is yet to condense enough to be physically visible to others.

It's similar to looking into the sky at distant stars. Because of the lag of the speed of light, you only see the light from the stars many years after it left those stars. So you are seeing those stars as they were, not as they are now. By looking at the stars, you are looking into the past, not the present.

So why is this important to your question?

It's because when someone asks you about your manifestations, you are perfectly entitled (without being untruthful in any way) to talk about your current vibrational reality rather than the in-the-past physical reality around you. You can tell them all about the details of your vibrational job and how much you are enjoying it.

And the bonus of doing this is that the more you do give your attention purely to that vibrational reality (through talking about it, or otherwise), the quicker it will condense anyway.

Of course, if these folks are currently so involved and intertwined in your daily life that they feel they have the right to demand to see physical evidence of your manifestations, then you may have to be a little more creative to keep them off your back. :)

Personally, I find the easiest way to avoid all these issues is to rarely talk about what my desires are to other people, and also avoid talking about what has already manifested for me.

To others, you just become that happy, lucky person who always seems to get good stuff out of nowhere. Sooner or later, some of those folks may start asking you why you are so lucky all the time...and then you can start being more upfront about what you are up to. Until then, it's better to stay silent about it all, in my view.

In any case, you'll find that it makes it so much easier for miracles to happen in your life when you don't have the thought at the back of your mind that you ever need to prove anything to anyone.

It lets you be much freer in allowing whatever is coming to come, and gives you the freedom to change your mind about what you want as often as you like without feeling a need to justify your new desires to anyone else.
