Psychologically, we sometimes need to be aware of our feelings about death.
The obvious image of the skeleton appearing in our dreams forces us to be aware of this.
It can also suggest feelings or talents that we have forgotten and that, therefore, seem to have died.
To be conscious of our own skull in dreams is to appreciate the intellectual structure that we have given our lives.
To perceive a skull where there should be a head suggests that we are not using our intellectual abilities as well we might. When a skull is talking to us, a part of us that we have rejected or denied is beginning to ‘come back to life’.
To be talking to a skull is recognizing the need to communicate with those who are lost to us in any way; if we believe in life after death, we may feel that spirit is talking through the skull.
