In Jain dharma, a dream by itself is not considered paap, because it is not a deliberate action done with intention.

Paap is mainly attached to intentional thought, speech, or action done with attachment, desire, or wrongdoing. A dream can arise due to past impressions, habits, or karmic causes, but it is generally not treated as a conscious sinful act.

What matters is:

• whether there was intention,
• whether the mind was dwelling in desire while awake,
• and whether one later regrets, controls, and purifies the mind through vows, restraint, and meditation.

So, in short: having such a dream is not itself paap, but it can be a sign to become more alert and disciplined in thoughts and conduct according to Jain values.
