Scary stuff in my lucid dream-Help

Hi. I've had a couple of lucid dreams prior to this, but I had not realised what was going on in the first and in the other I got too excited. I was in what's supposed to be my English classroom (even though it looked nothing like it, which is why I went lucid), and had just noticed I was in a dream, so I got up and decided to see the current world that was in existence. Only, when I did, everything went black and there were lots of scary noises. Like a spontaneous death as soon as I tried to take over. I woke up straight afterwards, and later got back to sleep no problems. If there's any advice you guys have, I'd like to hear it.

In lucid dreams, realize there is no fear.
There is no point in fear.
You are in control, you are the puppet master. Don't let the fear happen, just be aware of your authority.
Things like this are more prominent to happen when you are a beginner, but as you progress, it will become easier to maintain power.

I have to agree with Erii....when you see or hear scary stuff, do your best to be brave. You are in control and you can fight whatever it is successfully. Most of the time, just standing up to it will be enough. You might also try asking what it/they want or what they represent. You might get some interesting answers. :)

Thanks for the help. The thing is it all happened so fast, it was all over in a couple of seconds. I didn't have enough time to try and take control and there was no entity that I could see to stand up to. Again, thanks for the help. I will ponder what this could represent.

Shout out like you mean it in the dream, it helps so much!
