If you have a dream about an elephant, you are most likely trying to retrieve a memory that you have lost. When someone says that they have the memory of an elephant or the brain of an elephant, they are referring to the fact that they are able to recall details of the past to an extent that, frankly, the vast majority of other humans are not. If you do happen to remember something very significant, then the presence of an elephant in your dreams may either indicate that you correctly recalled everything or that there is more information that you need to look for. If you haven't been challenging your memory recently, dreaming of an elephant may simply indicate that there is something significant you need to keep in mind.
The same concept is at play when you have a dream about a baby elephant, albeit with some slightly different details layered on top of that. For instance, if you have a dream in which you see a baby elephant, this could be interpreted as a representation of your desire to recall some memories from your childhood. Because we don't put in a lot of effort to remember what went on when we were kids, and because we don't practise doing this very often, some people find it difficult to actually recall what their childhood was like, or to recall certain events that occurred earlier in their lives. This is especially true for people who have trouble remembering specific details from their childhood.
In light of this, if you have a dream in which you see a baby elephant, you should consider the recent events in your life that have dealt with your recollections of the past. Have you recently reconnected with a long-lost relative who you haven't seen in a very long time? Maybe you ran into someone who literally just asked you nicely to try and remember some of your more distant past experiences and thoughts. Perhaps it was an old friend who made the attempt to bring up some of the earlier years that the two of you have spent together. No matter what the cause may be, attempting to recall fond childhood memories is a very plausible explanation for why you might be having dreams about a baby elephant.
Another possible explanation for why you might be having dreams about a baby elephant is that your short-term memory is playing tricks on you. If you dream of a baby elephant, it may have something to do with your short-term memory because of how your mind associates certain things. A baby elephant is short and small, so if you dream of one, it may have something to do with your short-term memory. Do you require my assistance in recalling something that took place in the most recent few days? Those few hours leading up to when you went to sleep? It's possible that you're not even aware that you need to remember anything, but your mind is trying to get your attention by bringing it to your attention that you have some kind of responsibility that you are not handling as well as you should be. This would be a good opportunity for you, when you wake up, to go over the events that happened to you in the past few days and think about why you might be trying so hard to recall the events of the past few days, or what you might possibly need to remember. This would be a good opportunity for you because when you wake up, you are going to have this opportunity. This is a warning that you are going to forget something important if you don't try to remember it now before it slips your mind completely. http://www.gotohoroscope.com/txt/dream-dictionary-baby-elephant.html
