It's symbolic, but something Freud seemed to miss out on is everyone's Symbol Set is different. It's your subconscious, and there appears to be some random neurological flashes in the brain when we're dreaming. So, it may be significant, or just random noise. Sleep is the mind's Reboot/Refomat/Defrag. What we're conscious of as dreams (We can remember) is just what floats to the top of that simmering pot of mashup.
Sorry, but I'm not going to lie to you. You're in your head with that. The brain that created that image. No one is more qualified to discern the meaning, if any. It wouldn't mean anything to anyone else.
She never stood up, or walked? It's possible, that it may have ment something about her staying put, not being able to leave. It's also possible that the mind just didn't think about her having feet, like normal legs normally do, so didn't remember to render them.
Do you have any foot fetish? That would significantly change the symbol set.
