Have you ever noticed that everyones house has a unique smell to it? Maybe I'm just weird lol but I love walking into other peoples homes and wafting in the wonderful scent in there home. This only applies to clean homes of course, but all the smells are unique and vary by house. Am I a crack pot or is this normal :(?

What's really weird is if you go on holiday for two weeks, you notice your own house has a smell too, when you get back.
The olfactory sense is among the more powerful in us, especially when it comes to being a memory-trigger. Semi recent studies into smells have almost definitely linked smell with deja-vu; that sense we've been somewhere before, or done something before, even if we know we haven't.
For example: There might be a smell memory of "grandma's house" locked away in memory, and when we enter another building, perhaps we pick this up, and it feels like we've been there before, even though we can't articulate why. Make sense?
Anyhow. Smell's crucial for us, and I smell things constantly. Uh, clean things, to be sure. :P
I love coming back from vacations to smell my home. So weird. But it's the scent other people link me to. It's almost comforting to know you have your own smell.
I personally like the smell of hotel rooms..haha
BTW, have any of you IIN readers ever come across this carpet cleaner powder stuff? I swear to God, IT SMELL LIKE CAT PISS! I smelled it in houses that have NO ANIMALS. It's an extremely, flowery perfumed carpet cleaning powder that really annoys me.
