"Psychic" visions from mother-in-law?

My partner's mother had asked him a week ago if I was pregnant, out of the blue; she said she had a dream about me giving her a grandbaby, but i really dont know how to respond or what to think. It is obvious that my partner and i dearly want this but i am not up for another BFN. She is not currently aware that we have been TTC for almost a year now. This cycle has me hopeful as i have been experiencing uncommon severe bloating (as in this is quite a new feeling to me), weirdly increased salivating, backache, nausea and just a general tired all the time feeling. No breast pain/changes whatsoever! I am 12 dpo atm and am dreading yet excited to take a hpt. Has this happened to anyone else? Where do I go from here??
