about a month after finding out what lucid dreams are i had one. and that is pretty amazing concidering i thought i forgot about it and figured i didnt want to do it (i was WAY wrong) it just sort of happened for me it was so amazing... dreams are just bland till u have had one. anyway thats about how long it took me. And to answer your second question i think it is possible, there have been people that have made up people that are just in their mind. And for ur last question i dont think that it would look exactly the same if u havent been there but from all the tv shows and pictures i think u could come way close. welcome to the forum!
