ljepotica,
Yep this is the sort of thing I've discovered too. The same number or "energy" as represented by that number (in your case it's looking like 7) keeps coming up again and again for us. It's like an
language of energies that we're having to figure out or pay more attention to now it seems.
I'm going to say something that may (hopefully not) sound strange to some but that usually doesn't stop me.
Many of us have come to Earth from what I'd call (for ease of communication) the 6th dimension or 6D. From what little I've remembered of it, it's a realm of sacred geometric shapes and energetic blue prints or building blocks for other things elsewhere. Barbara Hand Clow and others call this
"morphogenetic fields or M-fields". A much higher faster realm where
"Ideal forms that replicate life form in 3D" exist first as geometric forms and morphic fields.
I mention this because many people clearly carry this 6D awareness in them more so than others and I've noticed they resonate to sacred geometic images, numbers and number combinations, and
blue prints for things because of it. This
may be why some of us have this weird numbers language or consciousness in us and have to downstep that knowledge into physical 3D objects and senses.
What you said about....
"...I'll use them in conversation when describing quantity"....I found really interesting. Like we're using numbers in very different ways than what our conscious minds are aware of.
