You state that you have your empathy under control so im not really going to question you on that issue, although i would say lots of meditation helps and shielding also:)
The bringing of something back to life if im honest i have never really heard of such a thing only in Biokinesis but to my knowledge it is only possible with plant life one can speed up the plants growth and also take the plant in the other direction to a point of it whilting and dying off.
With you being in love with your best friend, is this because your friend is male? if so i think you may be a little confused and scared by your sexuality and the fact that you are afraid of other peoples reactions, if this is the case then may be talk to a trusted family member or teacher about this, everyone has the right to love freely regardless of sex,color or religon and should be able to do this without fear of being judged by society you will find that many here on this site are very accepting of others.
If however this is not the case then please accept my apologies.
Now about your dreams i suggest you looking into types of dreams to gain a better understanding of them and keep a journal to write them down in.
Hope this helps in some way:)
