Assumani,
Your dream of being in the hospital and having your blood drawn for someone else suggests that you may be feeling drained or depleted in some way.
The act of giving blood can symbolize a loss of energy, vitality, or even a sense of self.
It's possible that you're feeling overwhelmed or stressed in your waking life, and this dream may be a manifestation of those feelings.
Since this dream is accompanied by negative feelings and is classified as a nightmare, it's important to consider whether there are any underlying emotional issues that need to be addressed.
The dream may be a reflection of feelings of vulnerability, powerlessness, or a lack of control in your life.
It's possible that you're feeling like you're being taken advantage of or that your needs are not being met.
In the context of your previous dreams, it's interesting to note that you've also experienced dreams involving feelings of anxiety and fear.
These dreams may be connected to the same underlying emotional issues that are surfacing in your current dream.
It's possible that you're struggling with feelings of inadequacy or self-doubt, and these dreams may be a way for your mind to process and work through these emotions.
Overall, this dream may be a sign that it's time to take some time for self-care and reflection. Consider what areas of your life may be causing you stress or anxiety, and make an effort to address them.
It's also important to seek support from friends, family, or a therapist if you're feeling overwhelmed or unable to cope with your emotions on your own.
