The meaning of dream can vary widely because of how versatile hands are as a symbol, so it is up to you to decide exactly which of these dream meanings applies to you most.
According to popular theory, the left hand symbolizes feminine attributes while the right symbolizes the masculine, so if you find yourself using mostly your right hand in the dream, it could be an assertion of masculinity. The opposite is true if you mostly use your left hand in dreams.

If you dream that the hands in front of you are disembodies, or that your own hands are disembodied, then this may be a sign that you feel you are not getting yourself across well enough.

To dream about holding or touching hands with someone is usually indicative of romantic feelings toward that person, or love in general, however, dream interpretations suggest that it depends on how you are holding hands. For example, holding hands loosely and affectionately symbolizes love, but the dream interpretation of holding hands tightly might mean that you are scared of losing the person, or that you feel like they might drift away from you if you do not hold on tight to them.
If you dream that your hands are much larger than usual, this implies success, however if you dream that your hands are hairier than normal, this could mean that you are a coarse person. Hairy hands in dreams denote that you have handled social conflicts poorly recently and may need to take some time to re-evaluate the way that you've handled arguments.
If you are dreaming about washing your hands vigorously, it could mean that you feel that there is an issue that you are trying to work through, that you are trying to attain purity and relief from this issue.
