College 
To dream that you are in college represents transformations occurring within your circle of relationships and the outside world. Perhaps you are seeking higher education and intellect. You may be given an opportunity to follow a different course of action or to embark on a new journey. If you had gone to college in your past, then this dream may be tapping into those past feelings and emotions. However, if you are currently in college, this dream may mirror your present experiences and environment. You may be feeling a lot of pressure and anxiety.
Lecture
To dream that you are giving a lecture indicates that people around you find you devoid of fresh ideas - you are boring and uninteresting. Perhaps you need to work on enhancing your interpersonal skills. Alternatively, this dream may be a spillover of your rational, objective self.
Absence
To dream of being filled with the energy of absence means that you are unconscious of an emptiness within you.
Dreaming of feeling the absence of another person can represent an aspect of youself that is missing out on expressing itself. You may have a secret desire to travel, but you push it aside for the more rational idea of stability, etc. Look at the supporting images and emotions within the dream for clues.
Warning
To dream of a warning may be as simple as your unconscious mind making sure you are aware of a current happening in your waking life.
Heed any warnings in a dream, and check in with your emotions surrounding waking life warnings. Dreaming is often a way that more aligned aspects of yourself can offer important advice.
