Der Traumschlüssel (Svapnacintāmaṇi) des Jagaddeva
Whoever's lap is filled in a dream with money and goods, with choice fruits and blossoms, surely attains great fortune.
In the source Wessen Schoß im Traume mit Geld und Gut, mit auserwählten Früchten und Blüten angefüllt wird, der erlangt sicher großes Glück.

Ten Thousand Dreams Interpreted; Or, What's in a Dream
To dream of sitting on some person's lap, denotes pleasant security from vexing engagements. If a young woman dreams that she is holding a person on her lap, she will be exposed to unfavorable criticism. To see a serpent in her lap, foretells she is threatened with humiliation at the hands of enemies. If she sees a cat in her lap, she will be endangered by a seductive enemy.
