Dreams involving aliens can often symbolize feelings of being out of control or experiencing something unfamiliar in your life. The presence of the alien ships may represent outside influences or changes that feel overwhelming.

Laying in a tub naked can indicate vulnerability or exposure, suggesting that you may feel unprotected or open to judgment in a particular situation. The baby floating away might symbolize a loss of something precious, such as innocence or a new beginning that you feel is slipping away from you.

Being pulled out of the water by the alien ship can represent a sudden change or intervention in your life, perhaps from unexpected sources. This could indicate a feeling of being rescued or, conversely, being taken away from something you value.

Overall, this dream could be reflecting your anxieties about change, loss, and vulnerability. It might be helpful to reflect on any current life changes or circumstances that are making you feel exposed or out of control. Consider what support systems you have in place and how you might regain a sense of security.
