Interpretation 1 — Martha Clarke

Although apparently this dream has negative connotations, dreaming of getting disproportionately fat can mean that you feel strong enough to undertake major projects. Dreams of this type may also reflect a misdirected intimate impulse or an attraction or repulsion unconsciously accepted. On the other hand, it can also reflect the dreamer’s fear of gaining weight.
