I would tell them about the Brovado Effect,
how to lucid dream,
how to have astral vibrations enter your body,
tell them about the hidden world,
tell them about Jesus,
teach them love is the key,
tell them that the eye is the lamp of the body and if your eye is clear you will see your whole body as light,
and that you will be born into a world different than this one,
I would then encourage them to try and bend their light body and have total faith they can do anything within dreams,
If you open your heart and mind you will have angels come visit you and teach you,
that this is how you can go to Hogwarts,
to not be deceived when Satan comes and pretends to be an angel of light and corrupt you,
tell them the world has been lead astray and this is why in your life you will hear about Illuminati, bad organizations, and filthy rich families who are evil,
To sleep with one eye open (your third eye that sees the light at night during sleep),
To always keep your eyes and ears open,
to not be surprised when you start to experience a lot of déjà-vu becomes you are now a conscious dreamer,
and this makes your soul beautiful and that you now have an amazing gift many people are unaware of,
tell them they were born into the flesh and they are being born again into spirit,
and that because of this they are beginning to see the Kingdom of Heaven,
tell them the devil runs from the Holy Spirit,
and soon he will come and protect you, if Satan is trying to corrupt your heart because you are new to this world and are vulnerable,
to always make moral decisions because God is watching,
tell them now that they have seen the Kingdom of Heaven and have seen the Holy Spirit,
that they should never doubt the Holy Bible,
that this is what total faith is,
to then follow the Bible to the best of your ability,
that angels love all humanity,
and only the devil would tell you otherwise,
that humans are not good enough for God,
now that you are born again and have a soul to never sell it,
to never bow to evil,
to only feel bad for those who are unaware of this who are conditioned since birth Heaven and magic is not real,
that if you stay a really good kid you will always have angels willing to help you,
and even though Satan is still alive he dies soon and the whole world will be reborn, made new,
to love thy neighbour,
that angels have special powers they can gift you,
that God will reward you if you triumph evil,
that He gave me a Rod of Iron and a new name and I plan on giving it to you,
to not be defiled by woman!
etc etc I have to go eat Dinner!
Essentially I would teach him about Hogwarts and how to go to the other side of reality.
To always work on his brainwaves! His wavelength.
