I sense that you fear for your grandmas health and you have worries about your job. I also sense that you have grown to appreciate your grandma more because you, yourself feel and act more mature and feel grateful about your life.
I do not feel your dream is a psychic impression of a break in of your home, but rather, a reflection of your fear of losing her to her health. You also need to think of your home as your work, you must be feeling insecure or concerned about the foundation of what you do. I will tell you more about that later but first I need to let you know the different types of dreams you can have.
A physical life dream is a dream that is based on your physical life. You know the dreams I am referring to, the ones that you are flying, your teeth are falling out and you have no clothes on!
A spiritual dream is smooth, very positive and you either get a visit from the otherside and or a very positive message and you wake up refreshed and positive!
So please see your dream as a physical life dream ....displaying your fears about your grandma. It also reflects the work you do as an EMT.
You told me in your note that you are an EMT. If you got a call and by ambulance, had to respond to an elderly woman's home because of a health scare, you too would break into to the house to save her ...right? So this is also reflecting something about your job and your ability to do it.
To solve this, please address your concerns about your grandmother's well being by having a casual discussion with her. The information you receive from her, may calm down your fears and this reoccurring physical life dream will stop. You may also want to express your appreciation for her.
Secondly before you go to bed at night send a positive thought of good health and well being for yourself and all those you love. Feel the breath of positive thoughts creating an internal empowerment that you can sleep with positive thoughts. This action will allow the ever so power mind to rest at night and allow your spiritual dream to take over. I hope this helps. Please follow up with me and let me know!
