Bottle 
To see a bottle in your dream indicates that you are repressing your emotions when you should be communicating them with others. Pay attention to what is inside the bottle. A bottle of champagne suggests that you should mix and mingle more; get out and meet people. A bottle of poison indicates that you are harboring feelings of anger and malevolence.
To see an empty bottle implies that you feel emotionally fatigued and don't possess enough mental energy.
Baby Bottle
To dream of a baby bottle belies a desire to be cared for. You may have an expectation for somebody to give you the emotional sustenance that you require. There is a need in your life for self-nurture and to release the responsibility that you may feel.
Dreaming that you are feeding someone else shows a feeling of responsibility toward them or toward the situation that person represents.
To dream that you are feeding from a bottle may indicate a situation in your life that you have emotionally regressed within.
Bottled Water
Drinking bottled water in a dream indicates purity and cleansing. If you drank bottled water after an argument or other stressful situation in a dream, it symbolizes cleansing of your body and mind of the negativity associated with the situation you're facing.
Cans
Dreaming of a can indicates a store of possibilities that will provide emotional fulfillment long into the future. There may be many things that you desire to experience or participate in and dreaming of cans suggests that you may in fact get to experience most of what you desire throughout your life. Note the label on the can or cans for further insight into your unconscious.
Canal
To dream of a canal is reminiscent of a re-birthing experience, particularly if the canal is dark and covered, with a light at the end, like a tunnel.
Key Chain
To dream of a key chain is a symbol of opportunities about to become available to you. Note the type of decoration on the key chain - a sentimental object may mean the opportunity to succeed with a close colleague or family member.
Dreaming of a key chain dangling in a lock suggests a sudden surge of courage and the prospect of exciting adventure.
