I wonder if anyone knows if I for instance smell a particular smell that a spirit has given away as a signal for me - is it like a real smell? Do other people smell it too?

Or is it the way it is with suddenly hearing something that no one else hear?

The times before I have smelled something that I think is from spirit/s I have been alone, so I don't know.

Right now recurring is the same smell I woke up to from a dream months ago when I felt the presence of an elder lady (unknown to me) and two boys (also unfamiliar to me). It smells like a particular food and mixed in with what could then have possibly be the lady's personal smell. I've asked my daughter if she smells something different, food or something but she says she doesn't (I have not told her anything about the dream, lady, the boys), it comes and goes.
