Hello LiesLilith 
A lot of the symbols could be related to menstruation (moon phases, red, blood, emotions, shower/cleansing/releasing).
If this is not the case, then the dream could suggest that you are moving through some cycle or issue (full/crescent moon), perhaps emotional in nature (moon, red moonlight), which is draining you of energy (blood, vampire) and which you are trying to cleanse yourself of (shower).
Another possibility has to do with the balance between your feminine and masculine energies/aspects. There is a lot of feminine energy/symbology in this dream … the moon, your sisters, friend on bus, mother. It could be suggested that you are currently out of balance, and the only male symbol in the dream, the vampire, could represent your animus. The animus represents your masculine aspects, and in this case masculine aspects which have likely been ignored or unacknowledged. He may be threatening to possess you because you have ignored "him".
Do you need to incorporate/activate some of your masculine aspects/energies to gain better balance?
Are you feeling overwhelmed by emotions?
Are you feeling angry or guilty about something?
Are you feeling "drained"?
What do you think?
