? Yes, your posted output of this command looks strange.

What does that say.
I would also add that runlevel 5 in some distributions tells init to shutdown (in an orderly manner) AND power off (if the hardware supports power off).
Runlevel 0 will shutdown and halt the system leaving power on.

runlevel
runlevel(8) System Manager's Manual runlevel(8)NAME
runlevel - output previous and current runlevel
SYNOPSIS
runlevel [OPTION]... [UTMP]
DESCRIPTION
runlevel reads the system UTMP file, which defaults to /var/run/utmp when no alternate filename is given, to locate the most recent run-
level record.
The previous and current runlevel from that record are output separated by a single space. If there is no previous runlevel in the record,
the letter N will be substituted.
If no runlevel record can be found, runlevel outputs the word unknown and exits with an error.
During system boot, the environment variables RUNLEVEL and PREVLEVEL will be set by the init(8) daemon, these come from the runlevel(7)
event generated by telinit(8) or shutdown(8).
When these environment variables are set, runlevel will output the values from these instead. Thus runlevel can be used in rc scripts as a
replacement for the System-V who(1)-r command.
OPTIONS --quiet
Does not output the current and previous runlevel, nor does it output unknown in the case of error (but it will exit with an error
code).
This may be used to test for the presence of a runlevel entry, or to check for errors reading from the file.
EXIT STATUS
runlevel will exit with status 0 if a UTMP record was found, otherwise it will exit with status 1.
ENVIRONMENT
RUNLEVEL
runlevel will read the current runlevel from this environment variable if set in preference to reading from /var/run/utmp
PREVLEVEL
runlevel will read the previous runlevel from this environment variable if RUNLEVEL
was given, in preference to reading from /var/run/utmp
FILES
/var/run/utmp
Where the current and previous runlevels will be read from.
NOTES
The Upstart init(8) daemon does not keep track of runlevels itself, instead they are implemented entirely by its userspace tools.
A change of runlevel is signalled by the runlevel(7) event, generated by either the telinit(8) or shutdown(8) tools. This event includes
the new runlevel in the RUNLEVEL environment variable, as well as the previous runlevel (obtained from their own environment or from
/var/run/utmp) in the PREVLEVEL variable.
As well as generating the event, both tools write the new runlevel back to /var/run/utmp and append a new entry to /var/log/wtmp.
