The answer is unconscious erotic wishes.

Explanation:

Freud stated that all dreams are motivated because of wishes. As an example, children's dreams, as well as adults' dreams related to food or drink, are considered wishes' expressions that come from organic needs. Freud considered that comfort dreams, as well as sexual dreams, were also related to wishes.

However, most of the adults' dreams and some children's dreams are considered disguised expressions concerning some things that were repressed and in this way, wishes were unconscious. For example, parents usually do not allow children to handle knives. Thus, children repress their desires and they express them through dreams because desires became unconscious.
