I am in a cafeteria with a bunch of other students like myself. Theses vampires were telling us what to do and one of them jumped on me and was about to suck my blood from my neck. I asked the vampires where they could find a carus. they left and the kids shut the doors but the vampires came back and they were trying to get into the cafeteria. then the vampires held us hostage.
Dreams can often be symbolic representations of our subconscious fears and anxieties. In this dream, the cafeteria could symbolize a place of gathering or a social setting where you interact with others, suggesting that these feelings of vulnerability and being controlled could be related to your interactions with others in waking life.
Vampires are often associated with themes of power, control, and fear of being exploited or drained by others. Their presence in your dream could indicate a fear of being manipulated or controlled by others in your social circle or feeling overpowered by certain individuals.
The fact that you asked the vampires about a "carus" before they left could suggest a search for protection or a desire to overcome these feelings of vulnerability. However, their return and the subsequent hostage situation could represent your feelings of being trapped or powerless in a certain situation in your waking life.
Overall, this dream may be reflecting your fears of being dominated or controlled by others, as well as a desire to find a way to protect yourself and regain a sense of control in challenging situations. It may be helpful to reflect on any current stressors or conflicts in your life that could be contributing to these feelings of vulnerability and powerlessness.
