The one who lies about his dreams means here are some of the sahi ahadis from Al bukhari
‘Abdullah ibn Dinar, the client of Ibn ‘Umar, related from his father from Ibn ‘Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, “Among the worst lies is that he says that he has seen a dream which he did not have.”
‘Ikrima related from Ibn ‘Abbas that the Prophet, may Allah bless him and grant him peace, said, “Anyone who relates a dream which he has not really had will have to tie a knot between two grains of barley and will not be able to do so. Anyone who listens to people talking when they dislike him doing that or flee from him will have molten lead poured into his ears on the Day of Rising. Anyone who makes an image will be punished and have to breath a spirit into it but will not be able to do it.”
Sufyan said, “We have it connected to Ayyub.”
‘Ikrima related from Abu Hurayra, “Whoever lies about his dream.”
‘Ikrima was heard to say that Abu Hurayra said, “Whoever makes an image; whoever pretends to have had a dream; and whoever listens.”
‘Ikrima related that Ibn ‘Abbas said, “Listens, pretends to have had a dream, and makes an image.”
Hisham corroborated it from ‘Ikrima from Ibn ‘Abbas.
