A noumena is something that is unknowable. Noumina can not be experienced, or they cease to be noumena. A reported example would be the first person experience of another that is not shared with the person to whom it would be a noumena. It would be a phenomena to the person experiencing it, but a noumena to the person to whom it is "unknowable."

Is anything truly unkowable and isolated from the experiences of others? If someone on another continent plants a tree, I might not know the person nor be aware or the specific event, but I would, in a small way, benefit from that person's labors as a result of the increase in oxygen, decresase in pollution, and healing of the ozone layer that the tree contributes to. Furthermore, I could find out about the planting of the tree, but the fact that I do not does not eliminate the possibility that I could know about it.

If an elderly person in another country has a dream and forgets about it shortly after awakening, then dies shortly after that without making any contact with anyone between awakening and dying, it is unlikely that the contents of the dream woould be knowable to me at that point, nor have any effect on me. Yet, I know that people whom I have never met nor will ever meet have dreames that they forget. To me, this disqualifies it as a noumena.

If you believe in noumena, can you convince me that they exist?
