Hey everyone, the purpose of this thread is to gather an idea of how many people out there share a combination of these problems, as well as hopefully getting some insight into how some people have resolved these.
Two of my preferred induction techniques are WILD (tried many variations with success), and DEILD (either through alarms, or just waking naturally). For me, these two usually go hand in hand. I'd say 99% of my DEILDs/WILDs start with me standing up from my dream bed.
The first thing I usually do is stabilize, whether by rubbing my hands, shouting "STABILITY TO ME" or something silly along those lines, sitting down and rubbing the carpet, eating something... etc. Sometimes (I'd say most times) I have no problem stabilizing and continuing on with my dream.
Other times, not so much. I am occasionally faced with many problems, obstructions, "glitches" if you will. These include:

- Noticing one eye is closed, and when I try to open it, feeling like I'm opening my eyes IRL.
- Dream being too dark, unable to add brightness -> falling into the void, which in turn usually means the LD ends there
- Heavy body feeling. Arguably the most annoying one. Sometimes to the point where I fall to the ground and can't get up.
- Head spinning. This one usually accompanies the heavy body feeling. It almost feels like I'm drunk.
- Constant FAs. I keep "waking up" in my bed, usually ends up being a false awakening, and it means having to re-stabilize over and over.
- Lack of physical body - makes stabilizing hard in my experience (but doesn't happen as often for me)

These problems usually present together, and again, I have only had these during WILDs and DEILDs, never during DILDs. I would just like to hear people's input in this. I know some of these are common, but I couldn't find any explanation as to why these happen, how common they are, or an effective way of dealing with these.

I have two theories of why these happen (not exactly based on evidence, just really my gut), these are:
1) These problems might happen mostly in Non-REM lucid dreams. I remember reading a while ago something about non-REM dreams being shorter, fuzzy, related to not having a dream body, unstable.
2) The LD "golden rule", expectation is reality. Maybe I'm subconsciously thinking these will happen (e.g. I'm scared this LD will be unstable), leading it to become reality. I'm not too sure on this one though, because I do have many stable DEILDs and WILDs.

Anyways, I hope to hear from others on this topic.
