It was in Church and the veil was so long. His mother has white and grey hair.
Genearally, dreams don't mean ANYTHING- try last night for instance, I had a dream I was attacked by the merry men from Robin Hood. But if you don't believe that, then it probably means she's a little controlling (not nessicarily in a bad way), and if you two ever got married, she would probably try to make the wedding to her standards.
Means nothing other than you had a dream. Have a great day!
