Hey Jaka,
This dream seems to be about your feelings for Sandra and the anxiety you may be experiencing around her. You mentioned in your previous dreams that Sandra fell in love with you and you became a couple, but then there was a shooting and you were killed. This dream could be a reflection of your fears about getting into a relationship and the potential for things to go wrong.
The fact that Sandra approached you in the cafeteria but then didn't know what to say and left could symbolize your own uncertainty about your feelings for her. You may be worried that you're not good enough for her or that she won't reciprocate your feelings. Following her through the hallway and then having her disappear could represent your frustration and disappointment when things don't go as you hoped.
In your previous dream, you were able to protect Sandra and defeat the bad guys, but in this dream, you were killed. This could indicate that you're feeling less confident in your ability to handle challenges and protect the people you care about. It's important to remember that dreams are often symbolic and don't necessarily reflect reality. They can provide insight into our subconscious thoughts and feelings, but they don't always have a literal meaning.
Jaka, it's understandable to feel anxious about relationships and the potential for things to go wrong. It's important to remember that everyone experiences these feelings at times. Talking to a trusted friend or family member about your feelings can be helpful. You can also try writing down your thoughts and feelings in a journal. This can help you to process them and gain a better understanding of yourself.
Remember, dreams are personal and subjective, so only you can truly uncover the specific meaning behind this dream. Take some time to reflect on your feelings and experiences, and consider how this dream might relate to your waking life. If you have any further questions or would like to discuss your dreams in more detail, feel free to reach out. I'm here to support you.
