??? I have no idea!!

Let me start by saying I have no idea what I hope to gain from this post....
I guess I don't have anyone to discuss it with and I'm one to dissect everything!!

For 3 days now, I keep smelling a very strong cigarette/pipe smell.
All different times. Not just at home either... I smelt it in the car too.
None of us smoke so it's not coming from us...
It doesn't make me feel uneasy or scared. It doesn't give me comfort either. It's just there at different times and places...

Anyone else experienced this?
Whatever this is!

Yes, I have experienced this. It was only once though, I was looking at some pictures of someone who had passed away and suddenly had the sensation that I had cigarette smoke in the back of my throat, it was so strong!

I don't smoke and I even went to the windows to make sure the smell wasn't coming from outside. I believe it was that particular person's way of letting me know that they were still here. That's the only explanation I could come up with for it!
