The key symbol in your dream should help you determine what waking life issue/situation has generated your dream. Here's a link to its meaning on this website:

What woman in your waking life (alive or perhaps deceased) has made you feel as if they are responsible for casting you into a deep, dark pit? This "pit" might relate to an emotional state (a pit of despair, depression, etc) or it might relate to a social, financial or professional situation in which you feel as if you are alone, abandoned and/or unable to recover/escape.
As you have had this dream recurringly, think back to when it first started and what was going on in your waking life. Recurring dreams are always about unresolved issues. Once you identify the waking life catalyst of your dream and the identity of the woman, you can confront the issue consciously... which should make go away.
I hope that helps.
