Another dream I had the other day was me sitting on my bed and my mother came in and she picked up a leech and the leech was on hr finger. Please tell me what this one means as well.
Good morning, Stuart.
Rats represent betrayal (as in, "dirty rat"), and disease, while otters are generally considered playful. In your dream, you're trying to eliminate negative elements that you perceive within yourself. However, in your quest for honor, you lose your sense of fun. In general terms, this is a dream about maturing.
Your other dream seems to be saying that you believe someone your mother associates with is "leeching" from her - taking without giving anything back. It could even be that you feel this way about yourself.
Taken together, these dreams tell me that you may be feeling pressure to take on increased responsibilities at home. You want to be more responsible, but you are afraid that this means no more fun. While to some extent it's true that more duties mean less time for the pursuits of childhood, it's not true that they must be given up completely.
