I think it means you may be more open to the universal consciousness than you perhaps may think.
Tuesday my mother brought me home some Lavender seeds and a Lavender sapling to root, and try and grow.
Picking the Lavender and yellow flowers to me represents perhaps giving a gift. You have said you feel that the dreams end after you pick the flowers may signify to you picking them for yourself. I feel you are correct in this assertion as truly only you know what your dreams signify.
Personally my interpretation of it would be giving a gift to yourself.
Or in a universal context perhaps realizing in this instance that you yourself are a gift.
What a magnificent dream to have been blessed with.
