In a dream, just push and pull on a finger. It may be a little tricky because your palms are too tightly pressed. Then, you might not feel the full touch of your hand anymore...
The touch of yours is still there, even if it's like a tiny finger.
In a dream, focus your attention on the place in your psyche that is actually stored the experie of that kiss.
The touch of yours is still there, even if it's like this spiritual swirl.
