The Basin and The Channel
Scholars have said that dreaming of a full basin may indicate gaining honor and respect from a generous person, and performing ablution from it might signify escape from sorrow. As for the channel (qana), it may symbolize a household servant, illicit sexual relations, or relief and distress for the house's inhabitants.
