No, wet dreams aren’t considered spiritual attacks since they’re a normal part of human sexual development. That said, you should trust your intuition regarding your experiences and seek guidance if you think you’re being targeted while you sleep. This applies to any wet dreams that felt violating or overly aggressive.
You should approach wet dreams from a balanced perspective, taking all biological, psychological, and spiritual factors into account. This can reduce any anxiety around the topic and help you navigate any unresolved feelings.
