@FaeryWitch I've had this happen from time-to-time as well. Quite a few of my fur babies during this lifetime have crossed the rainbow bridge, and I am definitely open to them all coming back to visit me!
When I feel movement on the bed or something leaning against my leg, I always check to make sure it's not one of my cats - as they can be sneaky! If not one of my cats, I assume it might be one of my cats coming back to see me, or a member of my keep. I've actually asked my white wolf to sleep with me at night for protection.... and via the pendulum she has responded that she indeed sleeps next to me.
About 5ish years ago, I had a reading done... and I asked the medium if any family visits me. She told me a woman comes to see me every night and sits on the end of my bed to watch me sleep. How's that for creepy?! Lol!! Pretty sure this would be my grandmother if anyone. I used to wake up around 3 or so and sit up staring at the end of my bed. It was hard to not think about her sitting there after that reading.
Since I've never felt scared by these night time occurrences, I know it's nothing bad. Just someone checking on me.
