Recently began having seriously realistic dreams of being chased by someone or something that wants me dead in one fashion or another. I wake up with great difficulty breathing, gasping for air, my heart racing feelings of dread... these happen every 2-3 hours most of the night. Usually some time in the early morning I will finally fall into a deep sleep and sleep Ok for 3-4 hours, then it's time to get up and roll. Not feeling rested at all.
