  In this paper, we study the dynamics of subcritical threshold solutions for
focusing energy critical NLS on $\mathbb{R}^d$ ($d\geq 5$) with nonradial data.
This problem with radial assumption was studied by T. Duyckaerts and F. Merle
in \cite{DM} for $d=3,4,5$ and later by D. Li and X. Zhang in \cite{LZ} for $d
\geq 6$. We generalize the conclusion for the subcritical threshold solutions
by removing the radial assumption for $d\geq 5$. A key step is to show
exponential convergence to the ground state $W(x)$ up to symmetries if the
scattering phenomenon does not occur. Remarkably, an interaction Morawetz-type
estimate are applied.
