it's not a normal condition... sleep is a time of rest, you should be able to sleep easy,wake up peacefully... the only battle should be the desire to remain in your blankets a little longer
You should not approach sleep with dread. That's not normal. Not in the slightest.
I've had these dreams where I feel like someone is holding me down, smothering me, trying to control me... trying to attack me and pull me back down. I can tell you for a fact that it's not a dream, it's a spiritual attack. When I call on Jesus in that 'dream state', I ask Him to help me, save me, something happens, it's as if the battle shifts in my favour and I'm able to break away.
This isn't stuff to take lightly or try to explain with physical circumstances... stuff happens when we sleep that affects us when we wake up. I've had people tell me when we're praying about thing I had dreamt about... once I saw myself cutting my hair... I didn't tell anyone... a week or so later, two people who were praying with me asked me what I'd done to my hair. "physically" it was untouched, but spiritually man it was the wreck I had thought it was.
Guys... let's stop playing in the realm of what our eyes see... it's time to wake up (no pun intended).
Take this up with your local pastor... as in for real. Please!!! Stuff could be happening to you that's destroying you. Please!!!
