Help re possible vision please!

After my father died I had a very strong dream that my father, on his journey to the other side was in a coffin in a High Church with seven monks praying for his soul. It was an exceptionally clear dream and one that left a strong impression on my mind. Several weeks later I decided to go on a retreat to a monastery for three day's. This was a strange thing to do as I know no-one who has done such a thing and until the dream I had no idea about monks or their life, all I knew for certain was I had to go. I strongly felt God was calling me and couldn't wait to feel close to God and talk to him in private and to pray for my beloved father on his journey. My friends and family were concerned for me as they thought it was a very unusual thing for me to do and in fairness to them it was. I loved being on the retreat and felt uplifted, it felt that my soul ran before me in freedom each day, I felt I wanted to dance and laugh with happiness at being so near to God. The day to day running of the monastery was very disciplined and everyone could only speak one hour per day, I found this enforced solitude a comfort and I felt humbled. On the second day I was attending a service and the Abbot ran the church bell (as he did at the start of each service) and as I stood I was aware and sensed very strongly that something seemed to come into the church to join us, easiest way to describe it was something like a breeze. It seemed to come from out of nowhere and circled somewhat around the altar or and one part of the Abbey. I was keenly aware of it but thought I was imagining thing's. Then about ten minutes into the service as I was standing praying with my eye's closed totally relaxed and feeling at peace, a very strange thing happened. In my mind's eye, at a distance I could see a dot of a white light, the light seemed to grow as it moved very quickly towards me then Boom, I saw the face of Jesus as if on stained glass, clear as crystal right in front of me. I stared into it just long enough to confirm what I was seeing and opened my eye's as quickly as I could. But if I said to you, I saw it through my heart centre would you understand what I mean, it came from my heart although I saw it with my eye's. This all happened in a second but I nearly fell backwards in shock. I was too scared to tell any of the monk's what I had seen and sensed, incase they thought I was a lunatic, or it was my imagination plus I felt how could I a sinner tell such Holy men that I am there for a matter of day's and see something like that when they have dedicated their lives to Christ. I appreciate that it probably sounds like I have a fanciful imagination or grief distorted my view but I can assure you before God that I saw this. No part of the Abbey has stained glass nor was I reading anything of the like or seeing pictures to leave an impression like that on my mind. My question is what did this mean? I wonder was God responding to my prayers letting me know that he heard me. I am ashamed to say I am not a regular Church goer but do believe in him with all my heart, so why would I a sinner be blessed in this way? Sorry, I have taken so long to tell you this but I have'nt got a clue what it was supposed to mean and wondered if you would be kind enough to help shed some light on this matter?
