Chase 
To dream that you are being chased indicates that you are steering clear of a circumstance that you feel cannot be overcome. This is generally a metaphor for a kind of insecurity. If you dream that you are being chased by an animal, your anger that you haven't displayed or acknowledged is placed within this animal. You could also be trying to escape some primitive urge or concern.
To dream that you are chasing someone indicates that you are struggling to reach a challenging goal or aspiration. You could also be showing belligerence toward others.
Alligator
To see an alligator in your dream represents dishonesty, deception, and a false facade. It may indicate that you should step back and reevaluate your position or view of a certain matter. It may also represent your ability to move between the material world of waking life and the emotional, repressed world of the unconscious. In addition, the alligator can symbolize the ability and talent to cure or revitalize.
To dream that you are running away from the alligator denotes your refusal to face a distressing or upsetting matter. You may be harboring a negative feeling. There is some potentially destructive emotion that you don't want to admit you possess.
According to biblical interpretations, an alligator means that you will fall victim to the sin of arrogance and vanity.
Avocado
Seeing an avocado or holding one in a dream suggests that you are holding back from increasing your prosperity. Avocados are a rich source of nutrients, however seeing the whole fruit indicates that there is something holding you back from gaining more good fortunes. A halved avocado would indicate that you are taking the right steps towards prosperity although you are not quite there yet. You have doubts which may continue holding you back if you let them.
Crocodile
To dream of a crocodile suggests that you may be faced with an upcoming hazard or threat. Consider all suggestions that you receive from others before acting on them. These people may be leading you into making negative choices. The crocodile may represent a hostile or confrontational attribute that you possess. Perhaps you aren't projecting your true feelings to others.
To dream that you are chased or bitten by a crocodile indicates that you are experiencing failure and setbacks in your work and with relationships.
