I heard a voice while high?

I just started smoking recently, and so I'm pretty sure that I just kind of overloaded my body with THC/it built up a bit, but here's what happened:

Yesterday, I got pretty high with my friend around 1PMish. Later that night, at home, I decided to get high again out of boredome - this was at 6:30ish. I was baked, but for some reason it didn't hit me until about 15-25 minutes after smoking.

Then, at 1:30AMish, I once again decided to get high.. mostly just to relax me so I could sleep. I only smoked a little less than a full bowl.

The thing is.. about 25-30 minutes after smoking, and after I'd finished the peak of my high, I was just chilling on my bed.. and I started to hear this voice coming from the bedroom next to me.

You know that voice when you leave the phone off the hook for too long, and a recording comes on to tell you? Yeah, it was that voice.

There was no radio on, no one was talking in their sleep, and the phone was definitely not off the hook.

After the voice went away, I lay down and tried to sleep (still stoned), but I kept feeling like I was rocking and I was starting to feel sick. This morning I woke up and was mostly fine.. except that I kept getting that rocking feeling again. About three hours later I went to work, and an hour after that I was baked. I have no idea why. I work in a hot kitchen, and whenever I would go outside, I'd snap out of it.

For the rest of the night, I was in this sort of "haze".. I'm now also paranoid.. about everything. That there are "monsters" in the dark rooms and stuff. :| I got over that fear when I was 11 (I'm 14).

TL;DR, I know, and I probably won't get any replies on this.. but it made me feel better to tell someone. If anyone knows why I'm still feeling the effects of my bad trip, please tell me. I'm not overly concerned.. but it is a bit annoying.
