Venting to sleep

First attempt at sleep was very hopeful. Until a loud slam made my pulse rise. Second attempt I was tired and looking forward to get some sleep. But instead I hear my loud heartbeats through the pillow. Drumming. And then I hear child voices,and music. I know it's stressy caused hallucinations. But yet it continues. I'm so tired but I get no chance to sleep. My best bet is taking anxiety pills and try sleep again in 30 minutes.
