Istikhara For Education

Muslim scholars describe “Istikhara” on ask for goodness and willingness from Allah (Glorious is He). Free online Istikhara implies that once one anticipates a very important task, they are doing Istikhara before beginning and coming up with that task. Free online Istikhara is supposed as if one requests to Allah Almighty that, O My Lord, the Knower of Unseen guide me if this can be better on behalf of me and favorable on behalf of me or not?
I have decided to apply for another college program which is becoming an intervener for deaf and blind people. I really want to go into this program but I feel there’s something holding me back which is telling me I need to turn to Allah (swt) for guidance before I make the decision. So I made istikhara while I was in a state of not praying. In one of my dreams, it was confusing because I kept seeing and white and I can’t remember if there was green. It was just when I was in a room, it wasn’t very bright and half was dark and half was light, kind of, and during the dream there was just things that were and white. I really want to do this but now I feel worried.
