I started thinking. LDs happen inside your mind. If you go to i.e… your neighbor’s house in a LD, but have never been there IWL what would you see? Would your mind just generate random rooms and furniture or something? Yeah I know I could just check this myself but I haven’t seen LDs yet. Was just wondering what would happen?
A common occurrence is just, the house is generated randomly, hopefully following the taste of the inhabitants 
but since it’s a dream, results may vary greatly, from being a gateway to purgatory, to a military secret base . The undecided there tends to be pretty unexpected, so keep an eye out, and have fun 
Thanks for the reply tosxyChor ^^ This answered my question. 
EDIT: Just wanted to say I like your avatar, as I watch it passively it for some reason reminds me of Near from Death Note series xD
It does that even when I have been to said house 
But yeah, it will probably be random. Might even be close to the real thing providing you’ve gathered enough information subconsciously!
