What is the ruling concerning the fluid that is discharged after sleep or while awake, and is white and viscous or thick, or yellow and thick, and disappears from clothes after a short period, knowing that the questioner is constantly experiencing sexual dreams despite her avoidance of stimulants?

The normal secretions of a woman (vaginal wetness) are pure and necessitate ablution (wudu), not a ritual bath (ghusl). A ritual bath (ghusl) is only required upon certainty of the emission of semen. If there is doubt about whether the discharge is semen or something else, the woman may choose and assign to it the ruling she wishes.
