2 front teeth feel loose. HELP.?

about 4 days ago i notice that when i would put my fingers on my 2 front teeth and wiggle it a little, id feel them feel loose. also, there seems to be a little cracking wiggly noise coming from it. when i look in the mirrior, they dont seem to be wiggling. it could be paranoia, because ive been having dreams of my teeth falling out. i think i may grind or clench, but i cant see a dentist, so any home remedies for grinding also needed.
