Reading into Dreams
Freud
supporters would say that dreams are an outlet for the sub-conscious, and the
repressed emotions from childhood that lie there. A bad relationship or loss
of a close one during childhood, for example, can be repressed, and the anger
for the loss might be redirected towards the 'inner self', and only emerge during
dreams or through regression. Freud's theories are difficult to prove, but,
while they can not be disproven, they are very popular among many psychologists,
and the relevance of some dreams to our lives would indicate that they are of
some significance.
