iv seen something strange and got a bad feeling from it

Please excuse my spelling and grammer im dyslesic

Out walking one day,in woodland i saw like a small child with a large head, i know it wasnt a child, i felt it was following me, iv never felt so uneasy as if id see something i wasnt meant to and i needed to get out of there asap??

So you felt bad, like a negative feeling, that correlated with this small "child"? Don't be afraid to face your fear, call out to it and ask what is its purpose, and express your desire to make peace with it. If this is not possible, like perhaps a demon or negative spirit, then unless you have experience in repelling these force then stay away from any supposed curse areas in the woodland.
