Shalom,

I do not have a full answer, but what actually came to mind is a passage in Gitin 35a. The context is a widow who cursed Rabah bar Rav Huna, exclaiming, "May his chair be overturned." Out of concern for the force of her words, he literally overturned his chair and then set it upright again, apparently to fulfill the curse in a technical or symbolic sense. Nevertheless, the Gemara concludes: "Even so, he was not saved from the weakness that resulted from her curse."

This suggests that even when an outcome is formally or symbolically "satisfied," the deeper effect may still remain. The literal fulfillment did not fully discharge the experiential or metaphysical impact of what had been invoked.

While this is not a direct discussion of dreams or imagined enjoyment, it may point in the same conceptual direction: that partial, imagined, or technical fulfillment does not necessarily substitute for, or negate, the full realization of a matter. If so, it may be possible that enjoying something in a dream or imaginative state does not automatically remove the possibility of its actual fulfillment later.

I do not yet know of a clearer or more direct source that formulates this principle explicitly with respect to dreams, but bl'n I or someone else from the Kollel will try to let you know what else we can find.

May you continue to attain greatness in Torah and Yir'as Shamayim!

Bi'Vrachah,

Yishai Rasowsky
