Assalamu ‘alaykum,
I was recently informed of a very interesting website that has collected a number of books on dream interpretation (tafsir al-ahlam) and organized them in an easy-to-find, highly accessible manner.
Amongst the books included is Ibn Sirin’s Tafsir al-Ahlam (although many argue about this book’s attribution to the author) as well as Khalil ibn Shahin al-Zahiri’s al-Isharat fi ‘Ilm al-Ibarat and the more recent Ta’tir al-Anam of ‘Abd al-Ghani al-Nabulusi.
Here is the link:
