Aqueduct 
The appearance of an aqueduct in a dream is symbol of the dreamer's spiritual side.
Dead End
Dreaming of a dead end that is marked by a wall is showing that it may be time to re-evaluate a situation in your waking life. A dead end can indicate that a current situation is not working out quite as you may have expected and a feeling of disappointment is likely if you are to continue. To dream of a dead end that is marked by trees or an open space implies that there is another way to go that will produce a fruitful outcome.
Communion
To dream of communion indicates that you are experiencing a struggle with your needs and wants. Perhaps you are trying to sort out your feelings regarding the importance of possessions versus the need for emotional happiness. This dream may also imply that someone has been unfaithful or deceptive. Perhaps you want to fit in with a group or situation.
Racetrack
To dream of a racetrack is a caution to keep your options open. Putting all your energy into one project could unwittingly remove the focus from another project that may be more beneficial for you at this time.
Keep your energy clean and 'back more than one horse.' This is possibly related to career choice.
Procession
To dream about a procession signifies your readiness to stand up for your beliefs.
Laundry Chute
A laundry chute in a dream symbolizes a method of discarding old problems. There may be a past memory which you would like to forget or a part of your personality which you would like to put aside in order to focus on the present.
