Roz,
The bat is frequently seen as being a symbol of the darker or more private side of a dreamer's personality.
This is not necessarily anything evil, but often represents those aspects of one's personality which we would rather others did not discover about us, in case they might not like us because of them.
This has sometimes also been called the "shadow self".
shadow = dark = black?
A bat is blind but has a wonderful sense of direction all the same (by means of a mechanism of using extremely high frequency sounds much like using radar). Therefore a bat featuring in your dream may say that you are flying blind through your life, and are being forced to depend entirely on your instincts to get you through.
But the bat is also a symbol of free will or simply freedom itself, by way of it being a winged creature. Either the bat could be interpreted in your dream to mean that you are basically trying your wings and are getting out into the world in order to prove yourself to everyone concerned (including yourself), or alternately perhaps you should really think seriously about doing so.
Yes sometimes when taken in isolation a bat in a dream can represent a black messenger bringing omens or predictions of death, illness or a personal disaster, but it is important not to ignore the many other symbols which are seen in the same dream, whenever attempting to gain a greater understanding of what the bat actually represents to your dreaming mind (which could be something very different from what it may mean to the next person and so on).
You appear to have conveniently forgotten about the hallway, the shoes and the many other elements or symbols of your dream you have failed to mention, as though only the bat really matters to it's overall interpretation.
Do not therefore immediately jump to any premature conclusions that this must be a bad omen dream.
Hoping this helps,
