Hello. This is my first time ever on a forum so please excuse any mistakes

I was hoping someone could tell me what happened to me. Recently I did Reiki 1 and before our first attunement we did a visualisation meditation. Towards the end we had just finished visualising the crown chakra slowly opening and then were to imagine a white light from above and 'someone' coming down and presenting us with a gift-box we were to open. I was having trouble, no-one seemed to be there and nor could I seem to 'imagine' anyone. I was just about to try and imagine a box to open feeling abit sad no-one had 'appeared' with a gift for me when the most wonderful thing happened. The most wonderful surge of energy poured into me from the top of my head and down my arms and torso [not my legs]. It felt absolutely beautiful.
It was also emotionaly overwhelming and I cried from joy.

My whole upper body was just surging with this beautiful energy. Was this my gift from my healing guide? I don't know. Is this common? I really hope someone can tell me what this was.
