Is this actually sleep paralysis?

This happens to me repeatedly... A few times a week, almost every day.

I have the feeling of not being able to move while drifting off to sleep... But I don't sense a great weight on my chest or anything like that, my limb just feel very heavy and often I am still able to move the very tips of fingers. I usually move my fingers enough until I am able to wake myself up.

I rarely hallucinate, and when I do my eyes are always closed and its auditory. Either a demonic whispering, or hearing someone come through the front door of my house and walking up to me with heavy footsteps and stopping right in front of where I'm sleeping. I am never inimidated or scared, I actually find it quite interested and feel as if I could smile because I know it's all in my mind

This evening I had a nap and kept having this experience of not being able to move anything but the tips of my fingers. I also had what I believe was a false awakening? I got out of bed and went to the bathroom mirror and knew I dreaming since the reflection was blurry.

I wanted to tell myself I was dreaming but all I could say was "I'm drea--".. Something was preventing me from finishing the sentence, then I woke up.
This has happened on at least three occasions where I've realised I'm dreaming, but each time I have had little to no control and wake up right away.

I feel like I'm doing something wrong - I've had the aim of lucidity for a while and thought I would have managed it by now. Should I stop moving my fingertips when I'm feeling "paralysed"? It's feels almost instinctive to do it...

Sometimes I feel my body being very heavy. As if I was pinned down. And when I think about moving, I don't move. But not because I can't, but because I never give my mind a signal to move. I feel so comfortable, relaxed, almost as if i was drugged.

This feels totally different from when I had SP. Then, I really tried to get up from bed. I felt my sholders and muscles trying to lift up and move, tried to scream, but could not. I ddn't feel pressure on my chest, but I did see aliens around me.

So it's really up to you to decide what you had. But it doesn't really matter if you experienced SP or not. You don't need it to lucid dream, but if you have it, it will not hinder you either. Wheather you have it or not, just go on with your attempt. Here is a good WILD (sageous) tutorial.

You don't always have control in a lucid dream. And you don't have to say out loud "I'm dreaming". Just realizing it it's enough. It's common to wake up right away or after few seconds from a LD. Especially if you excited about it. That will get better with experience. Have you tried stabilizing?
