BC1969, i used to work construction and have had visions such as you seem imagine. Mostly leaping from heights, but also getting buried in holes. I still occasionally have nightmares about losing friends in structural failures. It's like watching the same crappy tv show over and over again but though it makes me uncomfortable my nightmares are not unbearable. i can't control my dreams but I can judge them using reason. You can judge you own dreams using reason, you have already given an example of you doing so.
Here is what I do, maybe you might try it-
Try earnestly and persistently praying to God for help. Getting down on your knees to pray won't hurt anything but your own pride. God knows what you need before you ask for it, ask anyway. If you don't know what you need ask Him. Pray on you knees every morning, begging for help. Then pray every night thanking God for the help He gave you. Every day on this side of the grass is something to be thankful for. I have Faith that if you ask God for help you will get help from Him. Be persistent.
