Hi Carson,
I'd go with "asleep".
Certain states of samadhi, especially when first starting out, may involve a "not sure where I've been" feeling, similar to sleep, as Riptiz describes.
Especially since (per your post, it seems - ? ) ... you're not experiencing samadhi (<- described below) regularly in meditation yet (?) -- this may have been the case (sleep-like samadhi) ... this sleep, or sleep-like dynamic is kind of the "segue" into samadhi, in my experience, and the experience of others I know, and is documented in yogic texts, as well.
The most common occurrence, when "segue-ing" into full readiness for samadhi, is to actually fall asleep. Then, bit by bit, awareness just kind of naturally remains, and you begin to remain aware, in a similar manner to spaces of inner silence when the mantra fades - but usually for longer periods of time, and with little or no body-awareness (this varies from person to person).
The next most common is to be in a sleep-like state - but to not actually have been asleep. This can usually be determined by either noting that there was some external consciousness (i.e. hearing the ice cream truck, etc.), or internal awareness - throughout, or "mostly throughout".
However, "samadhi proper", specifically nirvikalpa ("without mental constructs" - i.e. no subject, no object, no perception - awareness only) ... does involve awareness throughout.
I hope this is useful.
Wholeheartedly,
Kirtanman
