Urine coming out while sleeping

Q: I felt like my urine came out in my sleep. I touched my pants by hand but couldn't judge. I was feeling some dampness. I then touched the pillow and the blanket to get up and when I checked my underwear was slightly wet. I'm assuming it to be urine. I cleaned the phone etc as I touched it after touching my pants. What do I do about the pillow blanket etc. Are they impure as well. I didn't see any wetness but after touching my pants I touched the blanket and pillow.
