Feeling and attachment of not knowing the present moment

I was just meditating, and as I tried to see the breath more clearly, I noticed that there is this resistance again to doing that. When I tried to see that, it seemed to me that there was great pleasure above feeling and a comfortable feeling in the mind remaining as it is and not exerting itself to know the object in the present moment. The pleasurable feeling was very similar to the joy of laziness and comfort, or, for example, the comfort of a warm interior after coming in from the cold outside. I also noticed a tinge of sleepiness in it, although I just had eight hours of uninterrupted sleep. Have you noticed this previously? If yes, can you give details on what this is? This feeling is completely new to me, and I think it is an impediment in developing the mind. Thank you.
