Greeting and Blessing:
I received your letter.
With regard to the matter of dreams - in general, it is well known from various sources that there is no dream without some nonsense, even dreams that otherwise have some substance.
This is the answer to your question regarding the dreams that you mention in your letter, and whether they should be taken seriously in every detail concerning your activities to spread and strengthen Yiddishkeit, Torah and mitzvot.
Of course, a Jew does not require to be reminded in a dream about his great privilege and responsibility to spread Yiddishkeit to the fullest extent of his abilities, in fulfillment of the Great Principle of the Torah, V'Ahavto l'Reacha Kamocha. But it does have significance when one is reminded in a dream to increase such activities, especially as you write that you have the desire to dedicate yourself to this cause even more than before.
However, that detail which you mention about going to Great Britain, etc., to work there in the said direction, belongs to the part of dreams which, in the words of our Sages, is "nonsensical" and has no validity. For, every Jew has the opportunity to increase his activities in the area of spreading Torah and mitzvot, and all other good deeds, in his own place, and does not have to spend money and time to travel overseas to do that.
At any rate, it would be advisable for you to have your mezuzot checked to make sure they are kosher and properly affixed.
With blessing,
