A person's capture [asr] in a dream is a sign of good and provision. Isrār in a dream is retention of urine, and that is its meaning in the language too; and isrār [asrār, "secrets"] in a dream is learning of secrets. If he has lost something, he will be granted something better.
Whoever sees in his dream that he is a captive, there is no good in it in any case, and severe worry will befall him.
