A sopor is to sleep what a river is to a stream. It's sleep, just more so. If you spend your days tired and lacking the suggested eight hours, then a deeper sleep might sound like a good thing. But that kind of sleep is unnatural. It's not something that's going to be of benefit, in other words. If you even were to wake up, you'd probably feel groggy and agitated and that's not the point is it? And speaking of it in a spiritually symbolic sense, it's one step removed from the inherently negative quality that spiritual sleep in general, entails.
"For the heart of this people is waxed gross, and their ears are dull of hearing, and their eyes have they closed; lest they should see with their eyes, and hear with their ears, and understand with their heart, and should be converted, and I should heal them." (Acts 28:27) This verse is quoted from the book of Isaiah (6:10).
It's sometimes discouraging and disconcerting to see those who don't believe in God have more of a zest for life than the Christian. Jesus says that He came that we "might have life, and...have it more abundantly." (John 10:10) With reference to the Christian, there's no reason that we should be suffering needlessly through the mundane issues of life. It's not right to look at a clock and wonder why it is that time goes at the speed it does. Slow. They say to write what you know. And if I know anything, it's what it feels like to be, not only spiritually dull, but also one step down from seeing things the way they really are. Does this make sense? When I was in my late teens, I went from not seeing God at all (I was a Christian, even when I had doubts), to my eyes being opened and that's when I encountered the real struggle. The struggle to maintain my first love and the enthusiasm that came with that territory. If you were to ask me which one I preferred—to be spiritually blind, or just miserable because of what I do see, my answer would probably would on how I felt at the time. Yet if you were to remind me of my state by simply broaching the quesiton, I'd be reminded of the right answer: focus on God. Obviously, when we go about our life, spiritual acuity is of utmost importance. We've seen toto much to go back to sleep.
I also find that, the world may not necessarily want you back. Motive is so important. Look at the new Christian. They are so enthusiastic and joyful. Full of zest and zeal and they want the whole world to know what they've found, who they've met. It isn't just that the Holy Spirit has filled us with the fire of excitement and encouragement, part of what makes us want to "go tell it on the mountain" is that we want others to be happy. To have the peace and confidence and strength that come with knowing Jesus. But the same could not be said for many non-believers. There are those who preach the gospel of unbelief that truly do not have the best interests of the hearer at heart. It's not as if they're fighting for the downtrodden or blazing a trail through ignorance of behalf of the oppressed. They have a chip on their shoulder and, like a dog dreaming—are running in place, eyes wide shut. A spiritual sopor. One step down from being miserable plus Christian.
But then there are those who steadfastly refuse to believe and yet will still be your friend in spite of thinking you're a little nuts, a little crazy. But it's laughed off and appreciated as part of your quirkiness. This is a good thing. Listen to what Jesus says: "He that receiveth you receiveth me, and he that receiveth me receiveth him that sent me." (Matthew 10:40)
God can wake them through you.
