You can do them recently as me. But I think that your problem is that you are not giving attention to the RCs as you should. Every time you do a RC ask yourself "Am I dreaming?" And really mean it, not just tap your nose and test it. You need to have the intention, like imagine you have a strike of consciousness and you ask that and then you do a RC. Also try to have awareness of whats happening around you.

Thats the only problem if you do Lots of RCs, you do a lot and then your attention reduces, because its getting common. Try to fight that.

PS: I have no experience of that but that seems to be the prob.
