Suicide 
To dream that you commit suicide suggests that you have run out of ways to deal with certain problems or issues in your life. None of the methods are proving to be successful. It's possible that you are feeling remorse and instead of expressing those emotions, you are chastising yourself. On a more positive note, it may imply that you have found a way to discard negative emotions or qualities.
To see someone commit suicide in you dream indicates that you are worried for their well-being. Pay attention to the attributes this person may possess. They may represent similar aspects of your own personality that you want to get rid of. Maybe you detest this person's qualities and believe that if you possess similar traits, you want to discard them as well.
Canteen
To dream of a canteen implies that you prefer to select simple methods of mental satisfaction rather than expending too much energy.
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.

Nursery
