Abdullah bin Umar reported,

Last night I saw myself in a dream at the Kaaba, and there was a man of brown complexion, as handsome as any brown-skinned man you could see, with hair hanging down to his shoulders, straight hair dripping with water, resting his hands on the shoulders of two men as he circled the House. I asked, "Who is this?"They said, "This is the Messiah, son of Maryam."Then I saw behind him a man with tightly curled hair, blind in his right eye, the closest resemblance to Ibn Qatan of anyone I have seen, resting his hands on the shoulders of a man as he circled the House. I asked, "Who is this?"They said, "The false messiah, the Dajjal."Ubaydullah corroborated this, narrating from Nafi.

Sahih

وأراني الليلة عند الكعبة في المنام فإذا رجل آدم كأحسن ما يرى من أدم الرجال تضرب لمته بين منكبيه رجل الشعر يقطر رأسه ماء واضعا يديه على منكبي رجلين وهو يطوف بالبيت فقلت من هذا فقالوا هذا المسيح ابن مريم ثم رأيت رجلا وراءه جعدا قططا أعور العين اليمنى كأشبه من رأيت بابن قطن واضعا يديه على منكبي رجل يطوف بالبيت فقلت من هذا قالوا المسيح الدجال تابعه عبيد الله عن نافع
