To dream of the past, suggests that a current waking situation is paralleling a past situation. You need to learn from the past and not make the same mistake again. Alternatively, the dream may represent unresolved issues from the past. Or that you need to stop living in the past and look forward toward the future.

On coins, a ship ploughing through the seas is emblematic of joy and
happiness (8). But the most profound significance of navigation is that implied
by Pompey the Great in his remark: ‘Living is not necessary, but navigation is.’
By this he meant that existence is split up into two fundamental structures:
living, which he understood as living for or in oneself, and sailing or navigating, by
which he understood living in order to transcend—or what Nietzsche from his
pessimistic angle called ‘living in order to disappear’. The Odyssey is, basically,
nothing but a navigation-myth in the sense of victory over the two essential perils
of all sailing: destruction (or the triumph of the ocean—corresponding to the
unconscious) and withdrawal (regression or stagnation). Yet Homer reserves the
end of the periplus of Odysseus for a triumphant but affectionate ‘return’ to his
wife, his hearth and home. This is a mystic idea analogous to the mystery of the
‘fall’ of the soul into the material plane of existence (by the process of involution)
and to the necessity of its returning to the starting-point (evolution)—a mystery
which has been expounded by Platonic idealism and by Plotinus in particular.
This law of the returning soul corresponds to the belief in the concept of a
‘closed’ universe (like that of the Eternal Return) or the conception of all phenomena as a cyclic organization. Navigation, as envisaged in any philosophy of
the absolute, would deny even the hero his triumphant return to the homeland
and would make of him a perpetual explorer of oceans, under endless skies. But to come back to the symbolism of the ship, every vessel corresponds to a constellation (48). The ship-symbol has been related to the holy island, in so far as both
are differentiated from the amorphous and hostile sea. If the waters of the oceans
are symbolic of the unconscious, they also can allude to the dull roar of the
outside world. The notion that it is essential first to learn to sail the sea of the
passions in order to reach the Mountain of Salvation is the same as the idea
mentioned earlier in connexion with the perils of exploring the oceans. For this
reason Guénon suggests that ‘the attainment of the Great Peace is depicted in the
form of sailing the seas’; hence, in Christian symbolism, the ship represents the
Church (28). Some of the less clearly defined aspects of the symbolism of the
ship—comparable here with the small boat and the carriage—are related to symbols of the human body and of all physical bodies or vehicles; in addition to this,
there is a cosmic implication deriving from the age-old comparison between the
sun and the moon on the one hand, and, on the other, two ships floating upon the
celestial ocean. The solar ship frequently appears on Egyptian monuments. In
Assyrian art, too, ships shaped like cups are clearly solar in character; this cupshape narrows down still further the scope of the meaning (35). Another meaning,
sometimes quite independent of the foregoing, derives not so much from the idea
of the ship as such but rather from the notion of sailing; this is the symbolism of
the Ship-of-Death. Hence, many primitive peoples place ships on the end of a
pole or on the roof of a house. On occasion, it is the roof itself (of the temple or
house) which is made to resemble a ship. Always the implication is the desire to
transcend existence—to travel through space to the other worlds. All these forms,
then, represent the axis valley-mountain, or the symbolism of verticality and the
idea of height. An obvious association here is with all the symbols for the worldaxis. The mast in the centre of the vessel gives expression to the idea of the
Cosmic Tree incorporated within the symbolism of the Ship-of-Death or ‘Ship of
Transcendence’ (50).

Bodies of water represent your unconscious, your emotions, and your accumulated soul experiences. The ship in your dream could represent you and the ways in which you navigate through these parts of yourself. When interpreting this dream, consider the kind of journey and the type of ship. Some dream interpretation books say that if the journey is calm you should go forward with your plans. However, if it is a very stormy journey, get ready for an emotional upset or challenge.

In Christian symbolism the well falls within the group of ideas associated with the concept of life as a pilgrimage, and signifies salvation (4). The well
of refreshing and purifying water is symbolic of sublime aspirations, or of the
‘silver cord’ which attaches man to the function of the Centre. Demeter and other
deities were shown standing beside a well (15). But this symbol is found not only
in the higher cultures of Antiquity but also among the primitives. Schneider has
noted that, in the medicinal rites of peoples at the animistic level, the centre of the
scene is taken up by a lake or well in whose water the sick wash their hands,
breast and head. At the water’s edge, reeds grow and shells are to be found, and
both are signs of the waters of salvation (51). In particular, the act of drawing
water from a well is—like fishing—symbolic of drawing out and upwards the
numinous contents of the deeps (31). To look into the waters of a lake or well is
tantamount to the mystic attitude of contemplation. Finally, the well is also a
symbol of the soul, and an attribute of things feminine (32).

To dream that you are employed in a well, foretells that you will succumb to adversity through your misapplied energies. You will let strange elements direct your course.
