WW2 siren

[The_One]

 Ever time I've projected I never feel any vibrations. I was dreaming I was in school and got annoyed at a teacher, and stormed off. People where getting in my way and I said some thing scary. Any way I became lucid at this point and started to wake up. I had sleep paralysis and a blood really loud WW2 siren going off. I also heard a mans voice cursing me (couldn't see any thing but I wasn't going to hang around) so I flew straight up. The WW2 siren faded, but I still couldn't see. Just grey but, I would see a glitch of sight here and there.
So A:- why don't I feel vibration when I ain't that experienced, and B:- why was my sight grey or patchy?

P.s  I know the WW2 siren is astral wild life and Robert Bruce puts it.

Hi The One
Vibrations really are not any big deal. Some people report getting vibrations just before an OBE and some people do not get them. I get vibrations less than half the time before an OBE. IMO many people make too much of vibrations, because they are only a signpost that something astral may take place and Not an ironclad guarantee that an OBE Will occur.
