Yes this is usually a thought of impending trouble coming into your life could be true or false. I had a big bug crawling on me in a Holiday Inn once at 2:30 am. I got up and killed it, next day I had a car accident a coincidence maybe but I have heard this before.
maybe...
I have a buddy from Puerto Rico and he talked about these big ass lizards that come into the house some times. He said they were harmless but at night you can see them clinging to the walls and shit..There is no way I could sleep with stuff like that in my room.
In the Bahamas they have Anoles and I think geckos that run and down the buildings.
a few yrs ago, I was asleep in my bedroom, and then I hear a loud noise, like wings slapping on the wall. I didn't have my glasses or contacts, and I turned on the light and see what could be a bat or something flapping on the wall. I got out of the room and closed the doors.
in the morning it was gone...Weeks later I was vacuuming near my bed and went to pull something from the bed and felt something foreign and very odd...and yanked my hand back...turns out it was what was flying around...it was a huge ass Hercules Beetle, and it hid itself and then died...
