According to Jainism, your consciousness does not “go away” or travel elsewhere when you are dreaming.

In Jain philosophy:

• The soul (jīva) remains in the body during sleep and dreaming.
• During dreams, the mind and subtle mental activity become active, while the body rests.
• Dreams are seen as internal states arising from karmic causes, impressions, and subtle mental processes.
• So, dreaming is not the soul leaving the body; it is the soul experiencing mental activity within embodied life.

In simple words: Your consciousness stays with the soul in the body, but it becomes less outwardly active and more inwardly active in dream state.

Jainism also teaches that all experiences are influenced by karma, so dreams may reflect karmic impressions, past thoughts, fears, desires, or bodily conditions.

If you want, I can also explain this according to Jain terms like jīva, mana, and karma in a very simple way.
