I begin by agreeing with you that Satan remains continuously active in seeking to do us damage in our spiritual lives. It is wise to keep this in mind, as 1 Peter 5:8-9 encourages. I think I also agree that, at least to some degree, it may be said we have limited control over dreams. So to some degree, if erotic dreams are to be classified as sins, they might best be classified as sins of weakness or ignorance (rather than intentional or willful sins) and treated as such. We do well to echo David's prayer in asking for forgiveness for "hidden faults" and to be kept from willful sins (Psalm 19:12-13).

Perhaps it can be said that we are unable to control what we dream, at least directly. However, there are often, perhaps usually, conscious activities and thoughts that contribute to our having certain kinds of dreams. These could be sins that merit attention and, if dealt with properly, may help upgrade (or eliminate) our unwanted prayers. If we fill our minds during our conscious hours with thoughts that are sinful, these could contribute to our having erotic dreams. We are reaping what we sow. The instructions of Philippians 4:8-9 are always fitting and may help a lot.

Even if one should argue that an erotic dream should not be classified as sin, we should also recognize that if after we are awake again, we may sin by allowing ourselves to dwell on the dream, and relive it with an attitude of lust. We do well not to entertain the matter. And if we find that this kind of thing happens quite regularly rather than only occasionally, perhaps we should seek professional counsel. It could be a sign of something particularly unhealthy in our emotional or physical lives. And perhaps there are professional ways to counteract it.

Most appropriate, of course, is to include the matters in our daily prayers and, as we prepare to go to sleep at night, ask God to guard and keep our thoughts and innermost being even as we promise not to entertain or give wrongful thought to the temptations that may confront us. To be tempted is not a sin, but an unwillingness or failure to resist and reject the temptation is sin. May the comforting promise of 1 Corinthians 10:13 bring you joy as you move forward in Christ and deal with this.htmlect of life.
