Just the wierdest feeling , like telepathy

This was a long time ago,but I had a really strange experiance camping with a friend of mine. We were out behind my folks place in the pasture  surrounded by woods. Ihe sun was just starting to come up, and I woke up to a sound that sounde like a grian bin(dryer).That is a really unusual noise to hear in Indiana in the summer. As I reached to lift up the tent flap,I can remember the grass wet with dew.I`ts like I heard o voice in my head telling me to go back to sleep. A few days later I found like "core sample" holes in the field. About 4" around and maybe up to 2 ` deep. Pretty wierd for Mom and Dad`s couple acre`s out in the sticks. Iv`e had a serious interest in OFO`s ever since. Can`t read enough about `em.
Date of incident is approximate.  PD
