Welcome Jimmy,
I would never personally recommend the use of psychoactive drugs in order to open me up to such deep truths as these, as you just never know what is genuine, and what is either wishful thinking or the product of your own fertile imagination.
But that is only my opinion on the issue of ingesting drugs as a doorway to exploring my inner world, and not necessarily your own.
The only way which I know to help you determine whether the name SYLVAN is consistent with your life purpose is to do what is called a
name numerology reading.
Basically a numerologist (which I am not) which you are much more likely to find in the Numerology Reading forum when compared to your chances of finding one here, assigns numbers to each of the 26 letters of the English alphabet and then applies them to what is usually your birth name.
But I cannot see any valid reason why it should not also work with the name which you intuitively received while under the influence of that drug.
My suggestion for what it is worth would be to place this request instead in the Numerology Reading forum, and give yourself a much better chance of getting the reading which you are wanting, sooner rather than much later (or not at all).
One of the admin or board moderators may move your posting for you if you are willing to be patient for long enough, but if this fails then please use the following link instead to take you directly to the more appropriate forum.

I wish you well as you follow your own unique path through life,
