my wife experiences something like this; however when she feels it very extremely it is time to see a doctor. For instance if she starts to project her feelings on our pet, like she "knows" the dog has to go to the bathroom (as she has to go). THen it's time to see a doctor.

I would see a doctor if symptoms persist. Or if you have really vivid images. Or if unable to focus on anything but this. I have been there myself and you have to be able to spot warning signs.
