Transforming into a Cloud
Scholars have said that seeing oneself transform into a cloud raining money on people may indicate benefiting people. A cloud without rain, however, is interpreted differently based on the dreamer's status: it might signify an unjust ruler, an untrustworthy merchant, a scholar withholding knowledge, or a skilled craftsman whose expertise is needed. A cloud rising with thunder and lightning may indicate the appearance of an awe-inspiring ruler who threatens with justice.
