Very good dream.
Sai is helping you in your bad times, he is always with you.
But, there are few points or moments which you have forgotten to describe. I would like to give you few conclusions.
1. Lord shiva means a guru.
2. Temple means guru sannidhi or sai perview (boundary).
3. Security or guards mean devotees or followers of sai, ie., sai family.
4. Iam not sure whether you are having a Spiritual guru or not, but certainly you might have come across a guru whom your spirit has accepted but your senses or karma is not accepting. That is the reason you are running from sai (guru). But still he never loses a devotee, he is back of you to help you out.
Finally, i can tell you that you have come across a spiritual guru given by sai but your karma is not making you to accept him as guru. And another thing you knowingly or unknowingly been distracted by some other things where in you are not able to spend time for sai with whole hearted, a slight distraction of bhakti. Pls never leave him for your sake.
