If you do make one be very careful. A lot of countries have laws about what people under 18 can do online. Running afoul of those laws could get someone in a lot of trouble. Besides lying about your age and making an account anyway is an internet rite of passage.
In my 20’s I had three dreams. The first I was at my parents house preparing for a zombie invasion. I knew we would be fine if I found “it” (no idea what it was) but was unable to in the dream. The second dream I was at the office trying to find “it” again and knew I only had three chances. The third dream I was in the desert at the mouth of a skull shaped cave. I had a shovel and knew it was my last chance to find “it”. I failed and awoke knowing I had lost something important but undefinable. The dreams were all about a month apart and so vivid they felt real.
Another interesting note on my dreams is almost all of the really intensely real dreams I’ve been able to recall take place in different parts of the same “world”. Sometimes in the dream I can recall other dreams and where they are in relation to the current dream, most often I make the connection after waking.
