Formations on a Tea Cup!

Other day I just made some tea and set it aside. When I came back to get it I saw all these formations on the top in the tea cup. This is the first time I had time even to notice such a thing. Anyways I thought it was worth taking a picture and here they are ...

This first one looked like a heart.

This next one looked somewhat like a Whale.


This one looked like a face of the bird with a beak and an eye in the middle.



just another picture of the bird face ....



This one looked like a diwali diya.


Am I hallucinating or is it for real ?!!! You be the judge !!!
