Shadow Person Looked Like Girlfriend

You say "my son" not "our son" -Is your girlfriend your son's mother? If not, it could be his mother checking on him - this sort of thing has been reported in cases where the person in question is still very much alive.

The chill might have occurred after because that's when the poster realized it wasn't the girlfriend?

These doppelganger stories are pretty common. I've had these experiences too. I don't know if it's always cause for concern. Proceed cautiously.

Greetings, Peregrine, and welcome to YGS,

You thought you saw your girlfriend. Your son sees an old lady. Your "girlfriend she said she saw her grandmother here." You suspect that the "old lady" and "your girlfriend's grandmother" are the same person. Have you shown your son a photo of your girlfriend's grandmother to confirm/deny this hypothesis? All you have is a guess you *hope* is right.

When pursuing the glimpsed individual, "I wanted... Just to get out of my apartment and not go back in." This is called a "gut reaction." On YGS, most of our regulars --especially those whose information has proven helpful to me over the years-- agree: trust your instincts. Human beings have a "fight or flight" response for a reason; something seems "off" so you avoid it & any potential danger. You experienced a moment of this, but you brushed it aside.

I do not care to speculate without sufficient data; however, the data in your narrative could be interpreted as one entity using familiar faces as a useful camouflage. You wouldn't question your girlfriend as a danger; your son may see an old woman as harmless; and your girlfriend would perceive her grandmother as a guardian spirit.

I do not wish to cause you alarm, here; I'm presenting a different interpretation of the descriptions you provided.

You girlfriend's grandmother may indeed have travelled to observe you, in the role of a protective spirit, to ensure that you are a good person to be with her granddaughter. The dead who are aware of their status have been known to visit places of significance to their families to check up on them, even if the deceased had never been to that place while alive. (I know of one that took off on its own vacation, post mortem, but that's not my story to tell.)

Should your son recognize a photo of your girlfriend's grandmother as his visitor, then you've got a lot less to worry about! Deal with that *first.*

Cold spots & inexplicable drafts are more common when an entity is drawing energy away from a location in order to interact (appear, influence people, move objects, etc.). As you'd already observed the motion of the entity, it seem odd to me that your chill occurred *after* you pursued it down the hallway.

Something is not right, here.

Best,
Biblio.
