That is a fairly standard Lupus symptom.
For me, I think I start sweating while asleep. Then I get cold from the sweat and wake up freezing. I have had to get up and not only change my clothes but also change my sheets on occasion. It seems to correlate with other inflammation symptoms. When my lupus is quieter and more under control, I am less likely to have night sweats. If you are "of an age" and female, it can also be a menopause symptom -- or can be a side effect of prednisone and changes in hormones.
Hope you feel better soon,
