"My wife is beginning to instruct me on means to retrieve dreams, and bit by bit, it does seem to be working"

Theodore Sturgeon's quote recommends that his wife is teaching him how to remember his dreams. He is open to her instruction and is finding that it is having a favorable effect. This could imply that his better half is helping him to become more familiar with his dreams and to keep in mind them more easily. It might also mean that she is helping him to interpret his dreams and to get insight from them. It is likely that his spouse is using some type of dream treatment to help him get a better understanding of his subconscious mind. Whatever the case, it appears that her instruction is having a favorable impact which he is beginning to benefit from it.
