Bathroom, also a public place, represents a place related to interpersonal and emotional relationships.
Bathing represents self-adjustment and change.
Take off your clothes and find that there is no water, which means that you are ready and have revealed your thoughts and wishes.
And water is a symbol of feelings, and sometimes it also represents money.
So this dream shows that you are ready to accept something, but you find that it is not what you want.
Feelings are not enough, or conditions are not mature.
