:) I am glad you received answers for this
Often times I pick up on the thoughts of those around me, as do they. Both my sister and I have had experiences where we answer each others thoughts, not knowing they were thoughts as we heard them out loud.
Sitting in class I can often here others complaining out loud how much they are bored, when I glancee at them their mouth is not moving even as I continue to hear it, they are thinking it and I am hearing it.
If anyone lives in your home or nearby your room, you may also be picking up on their thoughts.
