can't move

Hey everyone, newbie here.

I have not intentionally astral project but been times during sleep when it must have been as if I have anyways because of the experiences of it do not fit into usual dreams or lucid dreaming. I was so surprised the first times it happened.

What I find scary is that I can't move in this state. It makes me feel helpless. What makes it even worse is that there have been times there has been other people there so I feel rather vulnerable if something was to happen, considering. I've been lucky then so far.

Then it is as if I return to my body and sort of expand out of the inner body to the body I am in.

I have never suffered from sleep paralysis before, the time between me not being able to move in the dream and being able to be in control again in my real body has never frighten me. It is only the time when I am in the dream when I can't move til I get back that I find awkward and scary.

What should I think off and/or do to be in control of the body while in the dream?

Most times it has been like as if someone from my past has been with me and in the one dream when I could not see that someone I still sensed that someone was around somewhere. I have no idea if that someone was, is, into astral projections, but because of some things that someone said to me before and tried to show me I gather was into something of the spiritual kind.

I have thought if that someone is responsible somehow for all this? Or is that someone in it's own way trying to protect me? Could that be it? But only I can do it right, move my body in the dream like that? That someone can't force me? Or can it somehow "pick me up" somewhere while I am dreaming and doing this? If so how do I stop that someone from doing this?

I would really appreciate your advice.

Thank you for reading.
