Figurative of giving personal approval
If you dream of registering to vote or of signing up for something, then this represents a willingness to allow that, which you’ve signed up for, to influence your life. Consider what you are registering for so that you can understand what you are subconsciously saying “Yes” to.
If you dream of a cash register, see Cashier.
To dream that some one registers your name at a hotel for you, denotes you will undertake some work which will be finished by others.
If you register under an assumed name, you will engage in some guilty enterprise which will give you much uneasiness of mind.
