If, then, the child has motives for wishing the absence of another child, every restraint is lacking which would prevent it from clothing this wish in the form that the child may die, and the psychic reaction to the dream of wishing death proves that, in spite of all the differences in content, the wish in the case of the child is somehow or other the same as it is with adults. If now the death-wish of the child towards its brothers and sisters has been explained by the childish egotism, which causes the child to regard its brothers and sisters as competitors, how may we account for the same wish towards parents, who bestow love on the child and satisfy its wants, and whose preservation it ought to desire from these very egotistical motives? In the solution of this difficulty we are aided by the experience that dreams of the death of parents predominantly refer to that member of the parental couple which shares the sex of the dreamer, so that the man mostly dreams of the death of his father, the woman of the death of her mother. I cannot claim that this happens regularly, but the predominating occurrence of this dream in the manner indicated is so evident that it must be explained through some factor that is universally operative. To express the matter boldly, it is as though a sexual preference becomes active at an early period, as though the boy regards his father as a rival in love, and as though the girl takes the same attitude toward her mother—a rival by getting rid of whom he or she cannot but profit.
