A shift in the time space continuum?
I'm half joking and half serious because I really don't know. I wish you had gotten some posts on this as I would have loved to hear some ideas as well and forgive me I hadn't subscribed to your post so it is only just now that I realized you didn't receive anything. I've never really heard of something like this.
But lets see what we/I do know.
1. Three generations of women all felt something.
There is a link there
2. What causes dizziness?
Illness perhaps? sometimes being overwhelmed with energy, chemical, air...
3. Is your daughter old enough to be pregnant?
She would contain that extra link a 4th that may need attention to be given. Or is there a sibling perhaps? But to keep the link of no. 1 it must be a woman. Maybe a relative or friend that is like family in your circle.
4. The number 3 is is about communication and neutrality. A fourth would suggest creation.
5. Is it a premonition of sorts that the women in the family should be aware of?
Have come up with any ideas? Has it reoccurred since? My apologies for not getting to you sooner Catrina. I hope all is well and hope that you would update us on the situation.
