The deer in dreams would represent an emotional aspect of your own nature, one that relates to feelings of being 'a dear', that is, being nice, kind, sweet, helpful etc. The stop street, I assume, is a place where you or others might get on or off a bus. Thus the dream would be showing a situation in which you are on a course of action that would be taken by those who use a way of thinking such as most people would use regarding a situation you may be dealing with. In this situation you might find that being very nice, kind etc. is a questionable feeling to have. (what is this I am seeing?)
Because the deer is walking around, the feeling of being 'a dear', very nice and kind appears as a perfectly healthy, sound feeling. When looking again, that is on second view which is the True Self's improved view, the feeling no longer looks to be a livable one because the head, implying the logic or reason that governs or controls the feeling of being very nice, has been removed from the feeling.
Turning the corner, can suggest a turning point leading to a change in the direction your thoughts are headed. At such a time you can again see or believe in being 'a dear'. But at this time you may need to try very hard to ensure that this feeling again does not lose the reason that should control it. By writing the words "TRYING TO" in capital letters it is indicated that making this effort is very important for you.
Because the second deer has been referred to as a 'big deer', it might be assumed that the larger and smaller(?) deer could be male and female. This would emphasize that a feeling such as being nice, kind etc. can also come of a more or less reasonable perspective. The dream is showing that you need to make a big effort to protect a more rational feeling of being 'a dear. [Being very nice etc. when there is no rational reason to act this way is not too intelligent. An example would be situations in which you are just being used - where there is no reciprocation of favours or helpfulness. Being 'a dear' is important (a big deer) but is must be governed by reason.]
