Seeing Faces And Numbers Everywhere
Psychic and Paranormal
When I was young my mother would always have my sister & I mentally count, notice, look for, etc. all of the faces, intricate designs, etc. that we would see as we fell asleep (we started out with counting sheep to help us fall asleep as I believe other people were told to do, etc. ), when we were bored, etc. & progressed to deciphering faces, objects, etc. that where hidden in plain sight in on the ceiling, floor, walls, etc.
She told us that it would engage our minds & help to make our minds tired (easier for us to fall asleep), etc. instead of our minds being left to wander aimlessly & keep us awake.
She also taught us that what/whom we saw, deciphered, etc. were most likely people whom had lived (walked the Earth Plane) before & that they were stopping through to see their old homes, land, etc. & that we were catching glimpses of them during their trips, etc.; that just because we noticed these figures, etc. didn't necessarily mean that they had a message for us, were there to contact us, etc. & that seeing spirits, figures, etc. was actually normal because they had as much reason, right, etc. to be passing through as anyone or anything else since they existed long before we were born, etc.
It helped me to distinguish whether or not the sightings were specifically there for me to give me a sign, message of some sort, etc. or whether the sightings were just part of normal existence.
As for what/whom you are seeing & the number 4 I would recommend asking yourself if these images & number are of any relevance to you (life path number, birthday, number of children, etc.) if it is of no relevance to you then I'd say that they're just part of existence & isn't a message for you, etc.
Over time I find myself noticing tons of images, etc. everywhere, it can become distracting if you allow it to take precedence over whatever it is you are supposed to be doing (having a conversation with others in the room, working, etc.) so I try to limit my mind engaging for times when I am alone, not busy, etc.
It can be hard to limit once your mind becomes fully aware of all of these images, etc. in the same space as you (like not looking or acknowledging the sparkly blue & green giraffe in the room, etc.) but it will help you to deepen your deciphering & focusing (deciding if something is meant for you or if you are basically seeing it because you're abilities are expanding.) skills.
I apologize for the length of my reply.
I hope it makes sense to you.
Have a wonderful weekend
