The idea of sailing would imply taking a water based voyage. This seems to suggest that the scene could be saying that you have embarked upon a spiritual journey. The seven strangers indicate using a spiritual or sacred idea or way of thinking when on this voyage. This would confirm the idea of a spiritual journey.

How a dream is recalled when awakening is very important. Usually recalling a name gives importance and significance to an idea. You have been able to only recall the beginning and ending letters of a person?s name ? a person whose name would give significance to the seven strangers (as this person is one of the group of seven). You have been left to consciously fill in the name ? one that your mind could assume fits the need here. By coming up with the name, Pleiades, you have give significance to the spiritual idea being used ? but it may not be the same significance or importance given it by the True Self.

The name Pleiades allows for an association with the Seven Sisters, a star grouping of Greek mythology. This can imply that the spiritual idea being used has something to do with stars or astrology ? Or ? it may simply suggest a spiritual idea being used that is more myth than factual reality.

The dream does show that you have a particular destination in mind, Athens, Greece. This destination could emphasize the idea of a spiritual journey that is taking you to grounds of reasoning that relates with (Greek) mythology which again emphasizes the idea of myths. One notable point is that Greece is not the holy land for any Christian. {Are you perhaps pursuing spiritual ideas that are more New Age thinking?}

The white birds in your dreams can simply indicate a situation that is ?for the birds? ? a bit ridiculous. White birds would also represent a spiritual feeling or intent about which you are very innocent ? meaning also very lacking in knowledge. The massive flock would indicate that a certain spiritual idea or intent carries a lot of weight or influence with you and has strong ego backing.

Another interesting point to note is that the name Pleiades pertains to its nine brightest stars ? seven sisters plus the two parents. In other words, a belief  (the two parents) that is itself a myth has produced a sacred or spiritual idea (the Seven Sisters) that is still a myth.

In a physical level interpretation the seven strangers can represent someone who may be acting as a guiding light (the seven sisters are stars) but a light that Scripture would refer to as ?the light that is but darkness? because you are still in the dark when a star?s light seems noteworthy.
