Amoeba
May relate to blind urges; basic cellular processes in your body; fundamental levels of awareness – i.e. being barely aware of something, but acting instinctively, or it could relate to sperm or ovum or reproduction. This might also relate to feeling your way instinctively in what you are doing. Amoeba’s engulf their prey, and if you know this it might figure in your dream in some way.
