It's probably trivial and nothing more than my imagination, but sometimes when I am out walking in the woods I hear footsteps that sound as if they are walking right beside me or just behind me. I always turn to look and see no one there. Everytime it happens I always remember how my mom and I used to take her dogs on these long walks through the woods; I always wonder if it's somehow her way of letting me know she is still with me in some capacity and that she still remembers the time we spent together. I hope it is, but it's probably just my imagination. The funny thing is, my Grandma, who also used to go for these walks with my mom on an almost daily basis, experiences exactly the same thing when she is out walking. When my Grandma and I are out walking together, which we do several times a week, we've both turned around at almost precisely the same time because we're hearing those same footsteps.
